So we have a simple equation: 7-3x=12
To solve this equation and find the unknown value of X, we can put the X-s on one side of the equation and the numbers on the other side. When the numbers and X-s will switch sides, the sign will be reversed, from + to - and vice versa.
-3x=12-7
-3x=5
Divide both sides with -3.
3x/(-3) = 5/(-3)
x= -(5/3)
