Question

Solve the pair of linear equation graphically x-2y=0 and 3x+4y=20

Answer 1

Answer:

the answer is here

Step-by-step explanation:

the given equation of the straight line are

the point (0, 0) and (2, 1) lies on the straight line (1).

plot the points and join them to get the line (1)

the point (0, 5) and (4, 2) lies on the straight line (2).

plot the points and join them to get the line (2).

the intersection point is (4, 2).

therefore x = 4 and y =2 is the solution of the given equations.

hope this helps you.
