Answer:
I believe the answer would be step 1: 12x + 15 = 12, and step 2: 12x = -3.
Step-by-step explanation:
3(4x + 5) = 12, you would foil and do 3 times 4x which is 12x, then do 3 times 5 which is 15. So the result would be 12x + 15 = 12. And the step 2 that goes along with this answer. you would do -15 on both sides of the equal sign, so now you have 12x = 12 - 15 which is -3, so it would be 12x = -3

The answer is 68.8 because you need to look at the number in the tenth's place wich is 8 and if the number behind it is 5 or greater then u round it to a number higher if it's 4 or lower ( in this case 3) it stays the same. Hope that helped
