Question

EXAMPLE 8 Solve the following system of linear equations grap
x - y = 1
2x + y = 8.
Shade the area bounded by these two lines and y-axis.Also, determine this area.​

Answer 1

Answer:

x - y = 1 x - y + 1 X 0 1 2 Y -1 0 1 (ii) 2 x + y = 8 y = 8 - 2x X 0 1 2 Y 8 6 4 Solution is x = 3 and y = 2 Area of is x = 3 and y = 2 Area of DABC =1/2× BC × AD =1/2 × 9 × 3 = 13.5 Sq. unit.Read more on Sarthaks.com - https://www.sarthaks.com/250822/solve-the-following-system-of-linear-equations-graphically-x-y-1-2x-y-8-shade-the-area
