1 - First we need to get all the x values on one side and all the numbers on the otherside of the equals sign.
2 - We then need simplify the equation to get 1 x.
Solve 5x - 2= 3x + 7
1 - Remember, whatever you do to one side of the equation, you must do to the otherside of the equation. We want to get rid of the -2. In order to do this we can add 2. This is because -2 + 2 = 0.
5x - 2= 3x + 7
ADD 2 (5x - 2 + 2 = 3x + 7 +2)
5x = 3x +9
Now we need to get the x's on the same side, let's say the left hand side. In order to do this, we subtract 3x.
5x = 3x +9
SUBTRACT 3x (5x - 3x = 3x - 3x + 9)
2x = 9
2 - We now have the x's on one side and the numbers on the other. We next need to simplify so we can get x on its own. To do this we can divide by 2 because 2x/2 = x
2x = 9
DIVIDE BY 2 (2x/2 = 9/2)
x = 4.5
