Equations

Given equation:


\dag\quad\sf{3x-2=-2x-47}

In order to solve this equation, isolate x on one side of the equation.

Begin by adding 2x to both sides:


\dag\quad\sf{3x+2x-2=-47}

Add 2 to both sides:


\dag\quad\sf{3x+2x=-47+2}

Combine the like terms now:


\dag\quad\sf{5x=-45}

The next step is to divide both sides by 5 - and then, x will be all by itself on the left side of our equation. That was our goal, was it not?


\dag\quad\sf{x=-9}

We now know that the value of x for this equation is -9.
