Question

Find the value of y that makes each equation true for all values of x x+5+11x=12x+y

Answer 1

Ok, let's simplify the left side first by adding the x's together
We get:
12x+5=12x+y
So if we subtract 12x from each side, it cancels it out on both sides, leaving us with 5=y or y=5

If we plug that back into the original we simplified of 12x+5=12x+y, we would have: 12x+5=12x+5, which is true.  :D
