Question

1. The coordinates of the point of intersection of the lines ax + by = 7 and
bx + ay = 5 is (3,1) Find the values of a and b.​

Answer 1

Step-by-step explanation:

value of X is 3

and y is 1

put this value in both equation

3a+b=7.............(1)

3b-a=5..............(2)

b=7-3a.............(3)

put the value of equation (3)in equation (2)

27-9a-a=5

-10a=-22

a=22/10

and then put this value in equation (3) and you get your answer
