We are given:


-7x=-(3)/(4)x-5

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


4(-7x)=4(-(3)/(4)x-5)

When we do that, our simplified answer is:


-28x=-3x-20

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:


-25x=-20

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


(-25x)/(-25)=(-20)/(-25)

When simplified, the answer will be:


x=(4)/(5)
