Question

Find the number of solutions of the

following pair of linear equations

3x – 2y = 5 and 7x - 2y = 3


​

Answer 1

Answer:

Given equations are:

x+2y=5 ....(1)

7x+3y=13 .....(2)

Multiplying equation (1) by 7

7x+14y=35 .....(3)

Subtracting equation (2) from equation (3), we have

11y=22

y=2

Now putting y value in equation (1)

⇒x+2(2)=5

⇒x=5−4

⇒x=1

x=1,y=2
