Answer:
y = -6
Step-by-step explanation:
-28 = 4y - 4
4y - 4 = -28
4y - 4 (+ 4) = -28 (+ 4)
4y - 4 + 4 = -28 + 4
4y = -24
4y/4 = -24/4
y = -6
Answer: 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.
Hope this helps!
Thanks!
Have a great day!
