Question: x + 2x - x = -2x + 4
You simply need to combine like terms:
2x = -2x + 4
+2x +2x (moving all x's to the left hand side)
4x = 4 (divide both sides by 4)
x = 1

add like terms
x+2x=3x+-x=2x
Now you have 2x=-2x+4
Move the -2 to the other side, you will get
4x=4
Divide by 4
the 4 on both sides will cancel and your answer is x=1

x + 2x + (- x) = - 2x + 4
x + 2x - x = - 2x + 4
2x = - 2x + 4
2x + 2x = - 2x + 4 + 2x
4x = 4
4x/4 = 4/4
x = 1
The answer is x = 1
Insert the value into the equation
- - - - - - - - - - - -
Check
x + 2x + ( - x) = - 2x + 4
x + 2x - x = - 2x + 4
1 + 2(1) - 1 = -2(1) + 4
2 = - 2 + 4
2 = 2

x + 2x - x = -2x + 4
2x = -2x + 4 (the x and - x cancel each other out)
4x = 4 (add 2x to both sides)
x = 1 (divide each side by 4)

x + 2x - x = -2x + 4
combine like terms:
3x - x = -2x + 4
combine further:
2x = -2x + 4
Divide both sides by -2x to get all the variables on one side of equation:
-1x = 4
Divide both sides by - 1:
x = - 4

you combine like terms to get
2x=-2x+4
you bring -2x to the other side(when you do this you change the sign)
so it becomes
2x+2x=4
combine like terms
4x=4
then divide on both sides
x=1

assemble terms according to the power of x
x+2x-x+2x=4
4x=4
x=1
