Question

The pair solve the pair of linear equation 43 x + 67 y is equal to minus 2467 x + 43 y is equal to 24

Answer 1

43x+67y = -24........i
67x +43y =24..........ii
Adding both we get
110x +110y =0
x+y=0..........iii
x= -y............iv

Subtracting both we get
-24x+24y=48
x- y = - 48.....v

Adding iii and v
2x=48
x=24

By iv
y=-24
