Here is the equation: 
⇒
You need to get "x" by itself so minus 3 from each side
⇒ 
⇒ 
Divide 8 by 2
÷ 
x=4
So each 4 is equivalent to 4
Lets check:
⇒ 
⇒ 
So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7

x = 0, x = , x = -
since we have a product of factors equal to zero, equate each factor to zero and solve for x
x² = 0 ⇒ x = 0 ( multiplicity 2 )
5x - 7 = 0 ⇒ x =
3x + 2 = 0 ⇒ x = -
