7. -5a + 7 = -38
Please show your work

Step-by-step explanation:

We are given the equation:

We want to solve for a, so we must isolate a on one side of the equation.

7 is being added to -5a. The inverse of addition is subtraction. Subtract 7 from both sides of the equation.

a is being multiplied by -5. The inverse of multiplication is division. Divide both sides of the equation by -5.

Let's check our solution. Plug 9 in for a.

This checks out, so we know our solution a=9 is correct.
