Multiply both sides by 7.
Multiply both sides by 7.

Divide only the left side by 7.
Divide only the left side by 7.

Add 8 to both sides.
Add 8 to both sides.

Divide both sides by 7.

Answer 1

The first step in solving the equation \( 7(x - 8) = 49 \) for \( x \) is:

**Divide both sides by 7.**

This simplifies the equation to \( x - 8 = 7 \).

Answer 3

To find the second step in solving the equation \( -3(y + 6) = 21 \) for \( y \), we first need to perform the first step, which would be dividing both sides by \(-3\).

So the correct second step after dividing both sides by \(-3\) (which gives \( y + 6 = -7 \)) would then be:

**Subtract 6 from both sides.**

This leads to the equation \( y = -13 \).
