y= 3 which would be choice A, because both equations are going to be set equal to eachother, so with that you would put [tex]7y - 3 = 5y + 3[/tex]
subtract 5y from 7y, and add the 3 from the left to the 3 on the right. this would leave you with 2y=6 so in this case you would divide both sides by two to get the answer of 3 which is choice A.
