Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
5x - 7 = 18
Step 2: Solve for <em>x</em>
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(5) - 7 = 18
25 - 7 = 18
18 = 18
divide 5 both sides.
<u>x</u><u> </u><u>=</u><u> </u><u>5</u>
It can work well here to simplify inside parentheses first.
