Question

Which of the equations below represents the second step of the solution process?

Step 1: 15x + 21 = 39 -15x
Step 2:
Step 3: 30x = 18
Step 4: x=1.6
A 5(6x + 1) + 4 = 39 C 30x + 4 + 1 = 39
B 5(6x + 5) = 39 D 30x + 21 = 39

Answer 1

D bc you would add the -15x to the 15x nd keep everything else the same so it would be 30x+21=39
