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.
