Question

2x+3y=12 ; x-y=1 Solve the simultaneous equation graphically.

Answer 1

Solution
given by:- : 2x+3y=12 and x-y=1

●2x+3y=12

●x = (12-3y)/2

●When y=2, then x=3

●When y=4, then x=0

●We have,

●x-y=1

●x=y+1

●When y=0, then x=1

●When y=1, then x=2

●Clearly the two lines intersect at P (3, 2)
●Hence x=3 and y=2 is the solution of the given system of equations.
