Question

Please help! What does "x" equal?

Answer 1

x = 3

Explanation:

Substitute x for each answer until you get an answer equal to 2.

3 - 1 = 2

2 - 1 = 2

1 - 1 = 2

The only correct equation is 3 - 1 = 2, so 3 is x.

Answer 2

Answer: 3

Explanation:

Take your equation x-1=2

Now put 3 in for x

3-1=2

2=2

x=3
