**hy**, Sunday, November 7, 2010 at 12:01amfirst need to change all fraction into same D so 49x over 2(7x+1) can muliply by x over x become 49x^2 over 2x(7x+1.

change the third fraction also into same D by mutiplying by 2(7x+1) over 2(7x+1) so becomes 22(7x+1) over 2x(7X+1)

then just add n subrract the numerator while D stays same
