The first thing to do is to remove the 8 from the left side. You do this by dividing both sides by 8:
t = -32/8
t = -4
The answer is t = -4
Answer:
x = -3
Step-by-step explanation:
3x + 9 = 12x + 36 (rewrite)
3x - 12x + 9 = 36 ------> 3x - 12x = 36 - 9
3x - 12x = 36 - 9 (collect like terms)
-9x = 36 - 9 ( substract)
-9x = 27 (divide both sides for the answer)
-9 -9
x = -3
