Best ResponseYou've already chosen the best response.0First get y by itself in bottom equation > y = 1+x/2 Then replace this for y in top equation >x/3 + (1+x/2)/2 = 4 solve for x by combining fractions using common denominators...

Best ResponseYou've already chosen the best response.01+x/2 needs denominator of 2 > 2/2 + x/2 = (x+2)/2

Best ResponseYou've already chosen the best response.0(x+2)/2 * 1/2 = (x+2)/4 with me?

Best ResponseYou've already chosen the best response.0Then x/3 + (x+2)/4 = 4 to add these we need denominator of 12 >(x/3)*(4/4) + (x+2)/4*(3/3) = 4x/12 + 3(x+2)/12 = (4x + 3x + 6)/12

Best ResponseYou've already chosen the best response.0(7x+6)/12 = 4 multiply by 12 on both sides >7x + 6 = 48 x = 6

Best ResponseYou've already chosen the best response.0plug in 6 for x into that equation above remember whn we solved for y initially >y = 1+x/2 replace x with 6 >y = 1+(6/2) = 1+3=4
