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.

Hope this helps!

Thanks!

Have a great day!

sorry, i don't know i just need points, i'm new here. chao

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
