what number should be added to both sides of the equation x - 7/8 = -5
To solve the equation x - 7/8 = -5 and find the value of x, we need to add 7/8 to both sides of the equation.
By adding 7/8 to both sides, we get:
x - 7/8 + 7/8 = -5 + 7/8
Simplifying the equation, we have:
x = -5 + 7/8
To add -5 and 7/8, we need to find a common denominator. The denominator of 8 is already common, so we have:
x = -5(8/8) + 7/8
x = -40/8 + 7/8
To add the fractions, the denominators must be the same. In this case, they are already the same, so we can add the numerators:
x = (-40 + 7)/8
x = -33/8
Therefore, the value of x is -33/8.
By adding 7/8 to both sides, we get:
x - 7/8 + 7/8 = -5 + 7/8
Simplifying the equation, we have:
x = -5 + 7/8
To add -5 and 7/8, we need to find a common denominator. The denominator of 8 is already common, so we have:
x = -5(8/8) + 7/8

To add the fractions, the denominators must be the same. In this case, they are already the same, so we can add the numerators:
x = (-40 + 7)/8
x = -33/8
Therefore, the value of x is -33/8.

To combine the terms on the right side of the equation, we need to find a common denominator. The denominator of 8 is already common, so we have:
x = -5(8/8) + 7/8
x = -40/8 + 7/8
To add the fractions, the denominators remain the same. Therefore, we can simply add the numerators:
x = (-40 + 7)/8
x = -33/8
Therefore, the value of x is -33/8.

What is the value of x in the equation x + 0.97 = -2
To solve for the value of x in the equation x + 0.97 = -2, we need to isolate x by subtracting 0.97 from both sides of the equation:
x + 0.97 - 0.97 = -2 - 0.97
Simplifying the equation, we have:
x = -2 - 0.97
To subtract the numbers on the right side, we can find a common denominator. The denominator of 1 in 0.97 can be written as 100/100. So, we have:
x = -2 - 0.97(100/100)
x = -2 - 97/100
Next, to combine the terms on the right side of the equation, we need a common denominator. The denominator of 100 is already common, so we can simply add the numerators:
x = (-2 * 100 - 97) / 100
x = (-200 - 97) / 100
x = -297 / 100
Therefore, the value of x is -297/100.
x + 0.97 - 0.97 = -2 - 0.97
Simplifying the equation, we have:
x = -2 - 0.97
To subtract the numbers on the right side, we can find a common denominator. The denominator of 1 in 0.97 can be written as 100/100. So, we have:
x = -2 - 0.97(100/100)
x = -2 - 97/100
Next, to combine the terms on the right side of the equation, we need a common denominator. The denominator of 100 is already common, so we can simply add the numerators:
x = (-2 * 100 - 97) / 100
x = (-200 - 97) / 100
x = -297 / 100
Therefore, the value of x is -297/100.
What is the solution of the equation x - 9/4 = -3/8?
To solve the equation x - 9/4 = -3/8, we need to isolate x.
First, let's add 9/4 to both sides of the equation:
x - 9/4 + 9/4 = -3/8 + 9/4
This simplifies to:
x = -3/8 + 9/4
To add these fractions, we need a common denominator. The lowest common multiple of 8 and 4 is 8, so we can rewrite the fractions with the common denominator of 8:
x = -3/8 + 9/4
x = -3/8 + 18/8
x = (18 - 3)/8
x = 15/8
Therefore, the solution to the equation x - 9/4 = -3/8 is x = 15/8.
First, let's add 9/4 to both sides of the equation:
x - 9/4 + 9/4 = -3/8 + 9/4
This simplifies to:
x = -3/8 + 9/4
To add these fractions, we need a common denominator. The lowest common multiple of 8 and 4 is 8, so we can rewrite the fractions with the common denominator of 8:
x = -3/8 + 9/4
x = -3/8 + 18/8
x = (18 - 3)/8
x = 15/8
Therefore, the solution to the equation x - 9/4 = -3/8 is x = 15/8.
