Question

the coordinate of the point of intersection of line ax+ by=9 and bx +ay= 5 is (3,-1) find the value of a and b ​

Answer 1

Answer:

a=4. b=3 _(1)

Step-by-step explanation:

ax+ by =5_(2)

bx + ay= 5

(3,-1) coordinate

x = 3 y.= -1

put the value of x and y in equation 1 and 2

3a-b=9 _(3)

3b-a=5_(4)

a= -5+3b

put the value of eq^n 3 and 4we get

b=3

a=4
