x=0

Explanation:

Because this is a proportion, you are going to cross multiply

Multiply -2 by x-5

-2(x-5)

Distribute the -2

-2x+10

Multiply 5 by 2

5xx2=10

Combining these gives:

-2x+10=10

Begin to isolate x by subtracting 10 on both sides of the equation

-2x=0

Divide both sides of the equation by -2

x=0
