Answer:
a = -2
Step-by-step explanation:
-3a + 8 = 14
First you want to combine the constants by subtracting 8 from both sides.
-3a = 6
Now you want to isolate a by dividing both sides by -3.
a = -2
Check your answer by plugging -2 back into the equation.
-3(-2) + 8 = 14
6 + 8 = 14
14 = 14
Your answer is correct.
Hope this helps!
