solve the system of equation graphically ; 2(x-1)=y and x+3y=15; . also find the co ordinates of the point where the lines meet the axis of y .

2x-2=y

when

x=0 , y=-2

x=1, y=0

x=3, y=4

now

x+3y=15

3y=15-x

y=(15-x)/3

when

x=0, y=5

x=1, y=4.6

x=3, y=4

therefore, from the graph drawn below shows that, the system of equations meet at a point (3,4)
