Question

Solve the following pair of linear equa inns graphically; 2x - 3y = 12 2y-1 = x​

Answer 1

Answer:

(3,2),(-1,0) and (6,0)

step by step explainasion:

The given equations are:

2x+3y=122x+3y=12 and 2y-1=x2y−1=x ,

Solving both the equation, we have

x=2y-1x=2y−1 , Putting the value of x in other equation,

2(2y-1)+3y=122(2y−1)+3y=12

=4y-2+3y=124y−2+3y=12

=7y=147y=14

=y=2y=2

Therefore, x=2y-1x=2y−1

=x=2(2)-1x=2(2)−1

=x=3x=3

Hence, the coordinate at which both the equations intersect is (3,2)

From graph, we can see that the other coordinates are (-1,0) and (6,0).
