2 2/3

7 1/3

Answer 1

To solve for x, we need to isolate the variable on one side of the equation.

Starting with: -15 + 3x = 7

First, let's get rid of the -15 by adding it to both sides:

-15 + 15 + 3x = 7 + 15

This simplifies to:

3x = 22

Next, we can divide both sides by 3 to solve for x:

3x/3 = 22/3

This simplifies to:

x = 22/3

So, the solution for x is 22/3 or 2 2/3.
