set bottom equation to look like first one.
2x+4y=4
this equation is the same equation as the first just multiplied by 2. the answer is c. infinite solutions. you can plug in and solve:
solve bottom equation equal to y, you get y=-1/2x+1
plug into top equation
x+2(-1/2x+1)=2
x-x+2=2
2=2
because that is a true statement it is c. infinite solutions
