Question

Solve each of the following system of linear equations graphically
1.x+2y=3; 4x+3y=2
2. 2x+3y=8; x-2y+3=0

Answer 1

Answer:

(a) This pair of linear equation has a unique solution because their lines cuts at a unique point in the graph .

i.e. (x,y) = ( 4.6 ,0.8 )

(b) This pair of linear equation has a unique solution because their lines cuts at a unique point in the graph.

i.e. (x,y) = (1,2)
