Jonathon Rich · Answer 1

x = - 6

Step-by-step explanation:

I like to start off by simplifying the equation! Then, I use inverse operations to narrow it down until I reach the answer!

5x + 12 = - 18

5x + 12 - 12 = - 18 - 12

5x = - 30

5x/5 = - 30/5

x = - 6

Elsa · Answer 2

x = - 6

Explanation:

First we collect like terms

5x = - 18 - 12

5x = - 30

(because when both signs are the same we add them)

Then we decide both sides by five so that only x will remain

5x / 5 = - 30 / 5

x = - 6

Thus, the value of x is - 6
