Ответ:
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
Ответ:
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
