Question

{} Solve this if u can {}

Answer 1

the given equation are

X+2y=7-------(1)

x-y=4----------(2)

now from equation 2

X=y+4

substitute it in eq1

y+4+2y=7

3y=7-3

y=1

substitute y value in X=y+4

X=5

(X,y)=5,1

now we know that line is passing through origin (0,0)

the line equation formula is

y-y1=(y2-y1/x2-x1)x-x1

y-0=(1-0/5-0)x-0

y=(1/5)x

5y=X

x-5y=0

now equation is

x-5y=0
