Question

Which of the following would have infinitely many solutions?

3x = 6 + 3x
2(x + 2) = 2x + 4 4x – 5 = 3 (x – 4)
-X + 6 = x + 6

Answer 1

2(x+2)=2x+4

I'm not very sure but I hope this is right. I took geometry last year so my memory on it is funky :/

Answer 2

Below.

Explanation:

2(x + 2) = 2x + 4

2x + 4 = 2x + 4

Both sides are identical so we can replace x with any value we like and the equation will balance, so there are infinitely many solutions.
