PLEASE HELP ME??!!

Notice that there is 2y in the first equation and -y in the second. If we had -2y in the second equation, then -2y (in second equation) and 2y (in the first equation) would eliminate the y because they add up to zero.
The way we make the -y of the second equation become -2y is by multiplying the entire second equation by 2. We need to multiply both sides of the equation by 2.
2(2x - y) = 2(6)
We multiplied both sides of the second equation by 2 as shown above. Now we have:
4x - 2y = 12
Now the second equation has the -2y term that we need.
Now we rewrite the first
