(5x+6)/4 =5x+4
multiply both sides by 4 to cancel the 4 in the denominator.
5x+6=4(5x+4)
5x+6=20x+16
then combine like terms. when they cross over to the other side, the numbers pay a toll, which is, they change their signs.
5x+6=20x+16
6-16=20x-5x
-10=15x
divide both sides by 15 to isolate x.
-10/15=x
or
-2/3=x
