Question

someone, please help me. I need this done by today. Also, if you do do it, can you write part a and then part B​

Answer 1

Explanation:

Part A: step 1 is correct, step 2 is wrong. Right side of the equation should be 12 - 21 = -9

Part B:

-14x + 21 = 30x + 12

-14x - 30x = 12 - 21

-44x = -9

x = -9/-44 = 9/44
