Question

1/2(x+2y)+5/3(3x-2y)=-3/2 and5/4(x+2y)-3/5(3x-3y)=61/60​

Answer 1

Answer:

$\frac{1}{2}(x + 2y) + \frac{5}{3}(3x - 2y) = \frac{ - 3}{2} \\ \frac{x}{2} + y + 5x - \frac{2y}{3} = - \frac{3}{2} \\ \frac{11x}{2} + \frac{y}{3} = \frac{ - 3}{2} \\ 33x + 2y = - 9$

and

$\frac{5}{4} (x + 2y) - \frac{3}{5}(3x - 3y) = \frac{61}{60} \\ \frac{5}{4} x + \frac{5}{2} y + 5x - \frac{10}{3} y = \frac{61}{60} \\ \frac{25x}{4} - \frac{5}{6} y = \frac{61}{60}$
