Answer:
a = 2
Step-by-step explanation:
5a−12=−2
Solve :
5a = -2 +12
5a = 10
a = 10/5
a= 2
You want to try to isolate the a. First we add 12 to both sides so it turns out to be:
5a=10
Now we need to divide by 5 on both sides to isolate it. 10/5=2
a=2
5a=10
Now we need to divide by 5 on both sides to isolate it. 10/5=2
a=2
