To isolate the variable x, we need to cancel out the -7/8 on the left side by adding its opposite value, which is +7/8, to both sides of the equation.
Therefore, the number that should be added to both sides of the equation x − 7/8 = −5 is +7/8.
What number should be added to both sides of the equation x − 7/8 = −5 to find the value of x ?

What is the value of x in the equation x + 0.97 = −2 ?
To isolate the variable x, we need to cancel out the +0.97 on the left side by subtracting its value from both sides of the equation.
x + 0.97 - 0.97 = -2 - 0.97
This simplifies to:
x = -2 - 0.97
x = -2.97
Therefore, the value of x in the equation x + 0.97 = -2 is -2.97.
x + 0.97 - 0.97 = -2 - 0.97
This simplifies to:
x = -2 - 0.97
x = -2.97
Therefore, the value of x in the equation x + 0.97 = -2 is -2.97.
What is the solution of the equation x − 94 = −38
To solve for x in the equation x - 94 = -38, you need to isolate the variable x by adding 94 to both sides of the equation:
x - 94 + 94 = -38 + 94
This simplifies to:
x = 56
Therefore, the solution to the equation x - 94 = -38 is x = 56.
x - 94 + 94 = -38 + 94
This simplifies to:
x = 56
Therefore, the solution to the equation x - 94 = -38 is x = 56.
What is the solution of the equation x − 9/4 = −3/8
To solve for x in the equation x - 9/4 = -3/8, you need to isolate the variable x by adding 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 the fractions, you need a common denominator, which is 8:
x = -3/8 + 9/4
= -3/8 + 18/8
= 15/8
Therefore, the solution to the equation x - 9/4 = -3/8 is x = 15/8.
x - 9/4 + 9/4 = -3/8 + 9/4
This simplifies to:
x = -3/8 + 9/4
To add the fractions, you need a common denominator, which is 8:
x = -3/8 + 9/4
= -3/8 + 18/8
= 15/8
Therefore, the solution to the equation x - 9/4 = -3/8 is x = 15/8.

To solve for x in the equation x + 23 = 9, you need to isolate the variable x by subtracting 23 from both sides of the equation:
x + 23 - 23 = 9 - 23
This simplifies to:
x = -14
Therefore, the solution to the equation x + 23 = 9 is x = -14.
x + 23 - 23 = 9 - 23
This simplifies to:
x = -14
Therefore, the solution to the equation x + 23 = 9 is x = -14.
