Question

Solve graphically: x+y=5 and 2x+y=6​

Answer 1

Step-by-step explanation:

2x+y=6

⟹y=6−2x

Let, x=1, then y=6−2(1)=4

Similarly, when x=2,y=2

x−2y+2=0

⟹x=2y−2

Let, y=0, then x=2(0)−2=−2

Similarly, 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 =

Answer 2

Answer:

(1,4)

Step-by-step explanation:

Put x = 0 in both equation one by one and get corresponding y.

Then, put y = 0 in both equations and solve for corresponding x.

plot all the 4 points and you will get solution at point of intersection.
