Solve each of the following systems of eqautions by the method of cross-multiplication:

2x+y=35

3x+4y=65

2 x + y - 35 = 0

3 x + 4 y - 65 = 0

\frac{5}{x + y} - \frac{2}{x - y} = - 1 \frac{15}{x + y} + \frac{7}{x - y} 10,

\frac{2}{x} + \frac{3}{y} = 13 \frac{5}{x} - \frac{4}{y} = - 2

3 x + 2 y + 25 = 0

2 x + y + 10 = 0
