Answer 2

2x + 7 = x + 3

First, subtract x from both sides. / Your problem should look like:
`2x + 7 - x = 3`
Second, simplify 2x + 7 - x to x + 7. / Your problem should look like:
`x + 7 = 3`
Third, subtract 7 from both sides. / Your problem should look like:
`x = 3 - 7`
Fourth, subtract 3 - 7 to get -4. / Your problem should look like:
`x = -4`

Answer: x = -4
