Question

Using two or more complete sentences, describe and correct the error in the solution.

Answer 1

Answer:

In the very first step, when they multiply both sides by 3 the -2y should become -6y but instead it stays as -2y. The correct solution would be:

9x - 6y  =6

9x - 6y = 6

0 = 0

This means there are infinite solutions.
