Question

Can someone please explain? I don't understand

6(2x – 11) + 15 = 3x + 12

Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)

Part B: What value of x makes the equation true? (4 points)

Answer 1

A) Start by distributing 6 to (2x-11). Next with 12x-66+15=3x+12 combine like terms so you would have, 12x-51=3x+12. Next take -51 and add it to 12 on the other side. Then with 12x=3x+63 take 3x and subtract it from 12x. Then with 9x=63 divide by 9, and that gives you x=7.
