Question

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 = 15 Which of these is most likely the next step?

Answer 1

6x - 2x - 5 = -6 + 21
6x - 2x - 5 = 15
4x - 5 = 15
next step would be to add 5 to both side giving u :
4x = 20
x = 20/4
x = 5
