28 = 4y -4 solve for y and simplify

y=-6 and -6=y. *The answer should be the negative sign.*

Step-by-step explanation:

division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

a/c=b/c for c≠0

addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

switch sides of an equation.

4y-4=-28

add by 4 both sides of an equation.

4y-4+4=-28+4

simplify by equation.

4y=-24

divide by 4 both sides of an equation.

4y/4=-24/4

simplify by equation.

24/4=6

24/6=4

6*4=24

4*6=24

y=-6 and -6=y

It changes to positive to negative.
