Question

Draw the graphs of the pair of linear equations in two variables $x+3y=6,2x-y=5$. Find its solution set.

Answer 1

$x+3y=6$

$+(2x-y=5)3$

______________

$7x=21$

______________

$x=3;y=1$

writing equation in intercept form

$\frac{x}{6}+\frac{y}{2}=1$

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