Which of the following should be done to both sides of the equation x + 11 = −17 to solve the value of x ?
You should subtract 11 from both sides of the equation to solve for x.
To solve for the value of x in the equation x + 11 = -17, you need to perform the same operation on both sides of the equation. The operation required to isolate x is to subtract 11 from both sides of the equation.
So, subtracting 11 from both sides, we get:
x + 11 - 11 = -17 - 11
This simplifies to:
x = -28
Therefore, the value of x in the equation x + 11 = -17 is -28.
To solve for the value of x in the equation x + 11 = -17, you need to isolate the variable x on one side of the equation. The basic idea is to perform the same operation on both sides of the equation in order to maintain the equality.
In this case, you need to undo the addition of 11 to x. To do that, you can subtract 11 from both sides of the equation.
By subtracting 11 from both sides, the equation becomes:
(x + 11) - 11 = -17 - 11
On the left side, when you subtract 11 from (x + 11), the 11s cancel out, leaving x alone:
x = -17 - 11
Now, you can simplify the right side of the equation:
x = -28
Thus, by subtracting 11 from both sides of the equation, you can solve for the value of x and determine that x = -28.
