Question

solve by substituting method.....​

Answer 1

Answer:

Step-by-step explanation:

$\sf \frac {x}{2} + \frac{2y}{3} = -1 \:and\: x - \frac{y}{3} = 2 \\ \\ \sf From\: equation\:2 \: x = 2 + \frac{y}{3} \\ \\ \sf Putting\: this\: value\:in\: equation\: 1 \\ \\ \sf \frac {1}{2} ( 2 + \frac{y}{3} ) + \frac{2y}{3} = - 1 \\ \\ \sf 1 + \frac {y}{6} + \frac{2y}{3} = - 1 \\ \\ \sf 1 + \frac{y + 4y}{6} = -1 \\ \\ \sf \frac{5y}{6} = - 2 \\ \\ \sf y = \frac { -12}{5} \\ \\ \sf x = \frac{-2}{5}$
