Question

solve the pair of linear equation graphically 2x-y=2 and ×=2y-5​

Answer 1

Answer:

y=2

x=2y-5

x=2×2-5

x=4-5

X=-1

Answer 2

Answer:

Vertices of the triangle are A(2,2),8(3,0) and C(−2,0) and Area: 5 square units2x+y=6⟹y=6−2xLet, x=1, the y=6−2(1)=4Similarly, when x=2,y=2x−2y+2=⟹x=2y−2

Let, y=0, then x=2(0)−2=−2Similarly, when y=2,x=2

Plotting the above points on the graph, we get, the vertices of the traingle, i.e. A(2,3),B(3,0),C(−2,0)∴ Area of the triangle=21 ×5units×2units=5 sq. units
