We are given:

To clean up the equation, let's get rid of that fraction. To do that, multiply both sides by the denominator, which is 4.

When we do that, our simplified answer is:

We must isolate x on one side. To do this, add 3x to both sides. This will cancel the -3x on the right. When we do that, we are left with:

To remove the coefficient and get x by itself, we need to divide both sides by -25.

When simplified, the answer will be:
