Question

7/(x - y + 2) - 5/(x + y - 1) = 9/2; 3/(x - y + 2) + 2/(x + y - 1) = 4; x/(x + 1) - y/(y - 1) = 3; x/(x + 1) + (3y)/(y - 1) = - 1 10) (3x)/(x - 1) - 2/(y + 2) =

Answer

x-y+2=+; x + y - j = 7; 29/t / 29; 3/t + 2/7 = 4 2  7 t - 5 2 = 9 2; 14/t - 10/z = 9; 3/t + 2/z = 4; 15/t + 10/7 = 20; += 1 3 + 2 2 =4; t = 1; z = 2; x-y+2=1    bullet x-y=-1
