Question

Check whether the following equations are consistent or inconsistent. Solve them graphically in 5x-3y=11,-10x+6y=-22
​

Answer 1

Answer:

for example

Chapter 4 ) Pair of linear Equations in two variables.

Example-1) . Check whether the given pair of equations represent intersecting, parallel or coincident lines. Find the solution if the equations are consistent.

2x + y -5 = 0

3x -2y -4 = 0

sol) a1 = 2 b1 = 1 c1 = -5

a2 3 b2 -2 c2 -4

Since a1 =/= b1

a2 b2,

.^. they are intersecting lines and hence, consistent pair of linear equation.

The unique solution of this pair of equations is (2,1)
