Question

For which equation would x = 5 be a solution?

3x+6=21
12-2x = 13
7+ 6 x = 27
4x-7=27

Answer 1

No, for each equation x=5 would not be a solution.

If you plug 5 into x for each equation, only a couple of the equations would be true, while the others would be false.

Your answer is no

Answer 2

4x-7=27 is the answer to x = 5
