Question

2x+3y=4,x+3y=-5 give solution by cross multipacition method
​

Answer 1

$2x + 3y = 4 \\ \\ 2x = 4 - 3y \\ \\ x = \frac{4 - 3y}{2} \\ \\ \\ \\ \\ \\ \\ x + 3y = - 5 \\ \\ \frac{4 - 3y}{2} + 3y = - 5 \\ \\ \frac{4 - 3y + 6y}{2} = - 5 \\ \\ 4 + 3y = - 10 \\ \\ 3y = - 10 - 4 \\ \\ y = \frac{ - 14}{3} \: answer$
