Question

x+2y-4=0 and 2x+6y-12=0 solve graphically​

Answer 1

write equations in the form

$x - 2y = 4 \: it \:is \: equation \: 1 \: and \: 2x + 6y = 12 \: it \: is \: equation \: 2$

now in equation one put x=2 and solve then y=-1 will come on solving

similarly in second equation put x=0 then y=2 will come

now again in equation one put value of x=6 then y=1 will come on solving similarly in equation second x=3 then y=1 come

after this plot these point on graph and make a line

hence the line solve graphically
