3x + 3 = 5x - 30 -3x +3x 3 = 8x - 30 +30 +30 8x = 33 /8 /8 x = 4 1/8

Improved answer:

Let the unknown number be x:

3x+3 = 5x-30

3x-5x = -30-3

-2x = -33

Divide both sides by -2 to find the value of x remembering that a minus number divided into a minus number is equal to a plus.

x = 16.5

Substituting the value of x into the original equation will give you 52.5 = 52.5
