(-8x)<span> ÷ (-4)=0
First you have to divide both sides by -4:
2x</span><span> ÷ 1=0
Now divide both sides by 1 so that the left side can be eliminated:
2x=0
</span>Now divide both sides by 2 so that the left side only has x:
x=0
5 1/2 - u = 9/4 U= 13/4
Basically you have to get the variable (u) by itself. Doing this by doing the opposite of what it’s doing to both sides of the equation.
