What is the value of x in this equation? 5x + 12 = -18
siniylev [52]

Answer:

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 <u>− 12</u>= −18 <u>− 12 </u>

5x = −30

5x<u>/5</u> = -30<u>/5</u>

<u>x = -6</u>
