b)Multiply the terms in the bottom equation by 2 and add the resulting terms in the top equation to the terms in the top equation to eliminate x

c)Subtract the terms in the top equation from the terms in the bottom equation to eliminate x

d)Multiply the terms in the bottom equation by 4 and subtract the resulting terms in the bottom equation from the terms in the top equation to eliminate y
