x + 5 = 7
Now bring the 5 over to the other side so that X is by itself. Remember, the 5 changes signs ( + to -, or - to +) when it comes across.
x = 7 - 5
x = 2

1) Write your problem down.
2) Isolate for the variable you are solving for. In this case, x.
3) Check your answer.
1) x + 5 = 7
2) x = 7 - 5
3) (7- 5) + 5 = 7

x = 2.
You just subtract x from both sides.
x + 5 = 7
x + 5 - 5 = 7 - 5
x = 2
You can check by plugging it in:
x + 5 = 7
2 + 5 = 7
7 = 7 <== your solution works
