Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
9x - 7 = -7
Step 2: Solve for <em>x</em>
- Add 7 to both sides: 9x = 0
- Divide both sides by 9: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9(0) - 7 = -7
0 - 7 = -7
-7 = -7
You have given just one of the equations, and I guess you are looking for a formula for solving all linear equations.
I"d suggest looking at Cramer's rule for such a formula.

16.2 + 16.2 + 16.2 + 16.2
So your answer is 64.8
