Question

(4x+y=4) (3x-2y=14) solve the pairs of linear equation in two variables by graphical method

Answer 1

4x+y=4

y=4-4x

if x=1 , then y=0

x=-1 ,then y=8

x=0. ,then y=4

so for this you plot the points (1,0);(-1,8)and (0,4)

now do same for other equation and plot points . you will get two lines in each case . the point where they intersect, is the ans
