5.
the steps below show the incomplete solution to find the value of x for the equation 6x – 2x – 5 = –6 + 21:
step 1: 6x – 2x – 5 = –6 + 21
step 2: 6x – 2x – 5 = 15
step 3: 4x – 5 = 15which of these is most likely the next step? (4 points)
4x = 10
4x = 3
4x = 45
4x = 20
6. asher solved the equation below:
4x = 64
4x – 4 = 64 – 4
x = 60
is asher's solution correct? if the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (5 points)
