Question

the solution of equation ax+by+5=0 and bx-ay-12=0 is (2,-3).​

Answer 1

Answer:

a = 2 and b = 3

Step-by-step explanation:

2 a - 3 b = -5

2 b + 3 a = 12

6 a - 9 b = -15

4 b + 6 a = 24

subtract them

-13 b = -39

b = 3

putting the value of b in any equation we get the value of a

2 a - 3(3) = -5

2 a - 9 = -5

2 a = 4

a = 2

hence a = 2 and b = 3
