Question

Solve the system of equations graphically 2 -y=4,x-y=1 shade the region bounded by the lines and y axis find area of the shaded region

Answer 1

Answer:

y= 0

Step-by-step explanation:

2x-y=4,x-y=1,. when x=2 ,2x- y=4 ,2 (2)-y=4,y=0 ,when x=1 ,-2x-y=4 ,2(1)-y=4,-y= 4-2,y= -2 ,when x=0 ,2x-y=4,2(0)-y =4,y=-4 ,taking equation ,x-y =1 ,when x=1 ,-0-y =1 ,-y =1 ,y=-1 ,when x=2 ,x-y =1 ,(2)-y =1, -y = 1-2 , -y=-1,y= 1 ,when x=1 ,x-4 =1, (1)-4=1,-4=0,y=0
