1) 4x + 27 = 3x + 34
- subtract 27 from both sides (27-27 = 0; 34-27 = 7)
--------------------------
2) 4x = 3x + 7
- subtract 3x from both sides (3x-3x = 0; 4x-3x = x)
----------------------------
3) x = 7

put all the like variables together. Subtract 3x from both sides and subtract 27 from both sides and you get:

4x-3x+27-27 = 3x-3x+34-27
then you get:

4x-3x = 34-27
1x = 7
so x=7

1. 4x + 27 = 3x + 34
2. 4x + 27 -- 27 = 3x + 34 -- 27
3. 4x = 3x + 7
4. 4x -- 3x = 3x -- 3x + 7
5. x = 7

Minus 3x from both sides

x+27=34

x-27 = 34-27

x=7

proof:

4x7=28+27 = 55
3x7=21+34= 55

Hope that helps
