Question

{x+y/8=x+y/3
5x/3=-2y-1

Answer 1

$x + \frac{y}{8} = x + \frac{y}{3} \\ x - x + \frac{y}{8} - \frac{y}{3} = 0 \\ \frac{3y - 8y}{24} = 0 \\ - 5y = 0 \times ( - 1)$

$5y = 0 \\ y = \frac{0}{5} \\ y = 0$

$\frac{5x}{3} = - 2y - 1 \\ \frac{5x}{3} = - 2.0 - 1 \\ \frac{5x}{3} = - 1 \\ 5x = - 3$

$x = - \frac{3}{5}$

$S=( - \frac{3}{5} ,0)$
