Question

solve the liner equation:9x-4y=-14, 4x-9y=1 ​

Answer 1

Ans. Solve this equation by using elemination method

9(4x-9y-1)=0

36x-81y-9=0........(1)

4(9x-4y+14=0

36x-16y+56=0.......(2)

on solving equation (1) and (2) we get..

65y-65=0

So. Y=1

Now, putting the value of y on equation (2) we get

4x-9*1=1

4x-9=1

4x=10

X=10/4 on solving

x=5/2
