To solve the equation a - 2 = 8, we want to isolate the variable, which in this case is a.
Using the addition property of equality, we will add 2 to both sides of the equation:
a - 2 + 2 = 8 + 2
This simplifies to:
a = 10
To check our answer, we substitute a with 10 in the original equation:
10 - 2 = 8
The left side of the equation simplifies to 8, which is equal to the right side. Therefore, our answer of a = 10 is correct.
Using the addition property of equality, we will add 2 to both sides of the equation:
a - 2 + 2 = 8 + 2
This simplifies to:
a = 10
To check our answer, we substitute a with 10 in the original equation:
10 - 2 = 8
The left side of the equation simplifies to 8, which is equal to the right side. Therefore, our answer of a = 10 is correct.

To solve the equation 8.7 = 2.1 + b, we want to isolate the variable b.
Using the subtraction property of equality, we will subtract 2.1 from both sides of the equation:
8.7 - 2.1 = 2.1 + b - 2.1
This simplifies to:
6.6 = b
Therefore, b = 6.6.
To check our answer, we substitute b with 6.6 in the original equation:
8.7 = 2.1 + 6.6
The right side of the equation simplifies to 8.7, which is equal to the left side. Therefore, our answer of b = 6.6 is correct.
Using the subtraction property of equality, we will subtract 2.1 from both sides of the equation:
8.7 - 2.1 = 2.1 + b - 2.1
This simplifies to:
6.6 = b
Therefore, b = 6.6.
To check our answer, we substitute b with 6.6 in the original equation:
8.7 = 2.1 + 6.6
The right side of the equation simplifies to 8.7, which is equal to the left side. Therefore, our answer of b = 6.6 is correct.

To solve the equation -1.002 + x = 2.136, we want to isolate the variable x.
Using the subtraction property of equality, we will subtract -1.002 from both sides of the equation:
-1.002 + x - (-1.002) = 2.136 - (-1.002)
Simplifying on both sides:
x = 3.138
Therefore, x = 3.138.
To check our answer, we substitute x with 3.138 in the original equation:
-1.002 + 3.138 = 2.136.
The left side of the equation simplifies to 2.136, which is equal to the right side. Therefore, our answer of x = 3.138 is correct.
Using the subtraction property of equality, we will subtract -1.002 from both sides of the equation:
-1.002 + x - (-1.002) = 2.136 - (-1.002)
Simplifying on both sides:
x = 3.138
Therefore, x = 3.138.
To check our answer, we substitute x with 3.138 in the original equation:
-1.002 + 3.138 = 2.136.
The left side of the equation simplifies to 2.136, which is equal to the right side. Therefore, our answer of x = 3.138 is correct.

To solve the equation 13 = -y, we want to isolate the variable y.
Using the multiplication property of equality, we will multiply both sides of the equation by -1:
-1 * 13 = -1 * -y
This simplifies to:
-13 = y
Therefore, y = -13.
To check our answer, we substitute y with -13 in the original equation:
13 = -(-13)
The right side of the equation simplifies to 13, which is equal to the left side. Therefore, our answer of y = -13 is correct.
Using the multiplication property of equality, we will multiply both sides of the equation by -1:
-1 * 13 = -1 * -y
This simplifies to:
-13 = y
Therefore, y = -13.
To check our answer, we substitute y with -13 in the original equation:
13 = -(-13)
The right side of the equation simplifies to 13, which is equal to the left side. Therefore, our answer of y = -13 is correct.

To represent the English sentence "The value −2 subtracted from a number is 3" algebraically, we can write:
X - (-2) = 3
To solve this equation, we want to isolate the variable X.
First, we can simplify the subtraction of -2 by changing it to addition:
X + 2 = 3
Next, we can isolate X by subtracting 2 from both sides of the equation:
X + 2 - 2 = 3 - 2
This simplifies to:
X = 1
Therefore, the unknown number is 1.
X - (-2) = 3
To solve this equation, we want to isolate the variable X.
First, we can simplify the subtraction of -2 by changing it to addition:
