What I see here is that if I multiply both sides of the first equation by 4 then the yterm in bath equation will have a coefficient of 8.
Subtract the second equation from the first equation to get
Finally substitute x = 1/2 into either of the original equations to find x. I will substitute x = 1/2 into the first equation to get
Thus my answer is x = 1/2, y = 3/2. Now try your equations,
