Answer 2

Answer:

y=8

Step-by-step explanation:

To solve this equation, we need to find out what y is.

4= y-4

Therefore, we must get y by itself on one side of the equation.

4 is being subtracted from y. The inverse of subtraction is addition. Add 4 to both sides of the equation.

4+4=y-4+4

4+4=y

8=y

y=8

Let's check our solution. Plug 8 back in for y.

4= y-4

4= 8-4

4=4

The equation above is true, so we know our answer is correct.
