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.
The correct answer would be D -13
Answer:
2 is the factor of polynomial
It's a decimal, but you can rewrite it as a fraction: -8/10 or -4/5 (simplified).
