Question

Complete the Next Step: A partial solution to the equation 16 + 10x = 14x − 4 is given below. Choose the step that is missing from the solution.

16 + 10x = 14x − 4
16 = 4x − 4

5 = x

Answer 1

20 = 4x

12 = 4x

16 − 4x = −4

0 = 4x − 20

Answer 2

It would be your first option given: 20 = 4x.

Since that would be achieved by adding 4 to both sides from step 2. Then you would divide 20 = 4x by 4 on both sides to obtain the solution 5 = x.

Answer 3

thankyou!
