Which of the following should be done to both sides of the equation x + 11 = — 17 to solve the value of x?
A: add 11
B: subtract 17
C: add 17
D: subtract 11

Answer 1

To solve the equation \( x + 11 = -17 \), you want to isolate \( x \). To do this, you should eliminate the \( +11 \) on the left side of the equation.

To do that, you would subtract 11 from both sides.

So, the correct answer is:

D: subtract 11
