We have equation that we need to find the value of x.
6 – 2x – x = 18
Lets make some subtraction first of the variables.
6-3x=18
Put the variables on one side and the numbers on the other side. If a number or variable changes the side, he will have its sign changed from a + into a - and vice versa.
3x=6-18
3x=-12
Divide both sides with 3.
3x/3 = -12 / 3
x=-4
