they do not cancel each other out, one is positive, the other is negative
add y/7 to both sides
2y/7 = -2
divide by 2 and multiply by 7
y = -7
Solve 2+y/7+5=4+1-y/7 for y.
Book says the answer is y=-7
How can this be the answer when the y/7 can each other out when you simplify?
7+y/7=5-y/7
-7____-7
___________
y/7=-2-y/7
This is what I come down to.
