The answer is x = 78/5

<span>(1/5) (5x + 12) = 18
</span>
Multiple both sides by 5:
<span>5 * (1/5) (5x + 12) = 5 * 18
5x + 12 = 90

Subtract 12 from both sides:
5x + 12 - 12 = 90 - 12
5x =78

Divide both sides by 5:
5x/5 = 78/5
x = 78/5</span>

Answer: x = 78/5

Step-by-step explanation: You have to multiply both sides by 5, so

5 times (1/5) (5x+12)=5 times 18.

Subtract 12 from both sides:

5x + 12 - 12 = 90 - 12

5x =78

And divide both sides by 5.
