SOLVING EQUATIONS WITH VARIABLES ON BOTH SIDES
![Picture](/uploads/3/0/5/6/30566275/chalkboard_orig.png)
Please use the following setting out for your working:
3x + 2 = x - 4
3x -x +2 = x - x - 4
2x + 2 = -4
2x + 2 - 2 = -4 - 2
2x = -6
2x /2 = -6 /2
x = -3
Remember to keep the equation signs one above the other.
You may not need to use all lines of working but MUST include all lines in GREEN to gain full marks for a problem
