To solve for the value of x, we need to isolate x on one side of the equation.
Adding the same number to both sides of the equation will not change the equality, so we can add any number to both sides of the equation.
To specifically solve for x in the equation x - 7 = 1, we can add 7 to both sides of the equation:
x - 7 + 7 = 1 + 7
x = 8
Therefore, the number that should be added to both sides of the equation x - 7 = 1 to solve for the value of x is 7.
What number should be added to both sides of the equation x−7=1 to solve for the value of x ?

x−7=1
To solve for the value of x in the equation x - 7 = 1, we need to isolate x on one side of the equation.
To get rid of the constant term -7 on the left side of the equation, we can add 7 to both sides:
x - 7 + 7 = 1 + 7
x = 8
Therefore, the number that should be added to both sides of the equation x - 7 = 1 to solve for the value of x is 7.
To get rid of the constant term -7 on the left side of the equation, we can add 7 to both sides:
x - 7 + 7 = 1 + 7
x = 8
Therefore, the number that should be added to both sides of the equation x - 7 = 1 to solve for the value of x is 7.
What is the solution of the equation x−7=1 ?
To solve the equation x - 7 = 1, we can add 7 to both sides of the equation:
x - 7 + 7 = 1 + 7
x = 8
Therefore, the solution to the equation x - 7 = 1 is x = 8.
x - 7 + 7 = 1 + 7
x = 8
Therefore, the solution to the equation x - 7 = 1 is x = 8.

To solve for the value of x in the equation x + 11 = -17, we need to isolate x on one side of the equation.
To do so, we need to subtract 11 from both sides of the equation:
x + 11 - 11 = -17 - 11
x = -28
Therefore, the operation that should be done to both sides of the equation x + 11 = -17 to solve for the value of x is to subtract 11.
To do so, we need to subtract 11 from both sides of the equation:
x + 11 - 11 = -17 - 11
x = -28
Therefore, the operation that should be done to both sides of the equation x + 11 = -17 to solve for the value of x is to subtract 11.

To solve the equation x + 23 = 9, we need to isolate x on one side of the equation.
To do so, we need to subtract 23 from both sides of the equation:
x + 23 - 23 = 9 - 23
x = -14
Therefore, the solution to the equation x + 23 = 9 is x = -14.
To do so, we need to subtract 23 from both sides of the equation:
x + 23 - 23 = 9 - 23
x = -14
Therefore, the solution to the equation x + 23 = 9 is x = -14.

To determine which equation has a solution of -8, we can substitute -8 for x in each equation and see which one satisfies the equation.
Let's go through each equation:
1) x - 4 = -12:
Substituting -8 for x: -8 - 4 = -12
-12 ≠ -12
This equation does not have a solution of -8.
2) x + 3 = -11:
Substituting -8 for x: -8 + 3 = -11
-5 ≠ -11
This equation does not have a solution of -8.
3) x - 10 = 2:
Substituting -8 for x: -8 - 10 = 2
-18 ≠ 2
This equation does not have a solution of -8.
4) x - 8 = 0:
Substituting -8 for x: -8 - 8 = 0
-16 = 0
This equation does not have a solution of -8.
Therefore, none of the given equations has a solution of -8.
