Question

2x + 7 = x + 3 what is X ?

Answer 1

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
