Question

10/20
what is the correct step to solve for the variable?
$-15 = -16 + x$
subtract 15 from both sides
add 16 to both sides
add 15 to both sides
subtract 16 to both sides

Explanation:

Step1: Isolate x, eliminate -16

To cancel out $-16$ on the right side, we add 16 to both sides of the equation, since $-16 + 16 = 0$.
$$-15 + 16 = -16 + x + 16$$

Step2: Simplify to solve for x

Calculate both sides to find the value of x.
$$1 = x$$

Answer:

B. add 16 to both sides
