Question

Write a justification for each step.
16. 5x3 = 4(x + 2)

Answer 1

1.75 = x

Step-by-step explanation: I'm not sure if you meant 5x3 or 5 times 3 so I did the one that made sense

5 x 3 = 4(x+2)

First step: distribute so 5 x 3 = 4x + 8
Second step: 5 x 3 = 15 15 = 4x+8

Third step: Subtract 8 from both sides 15 - 8 = 7 7 = 4x

Fourth step: Divide by 4 on both sides 7/4 = 1.75 1.75 = x
