Question

If x =3 andy= 2 is the solution of a pair of linear equations ax- 2y =8 and x+ by = 5 then the value a-b =______________​

Answer 1

Answer:

a=4 and b=1

Step-by-step explanation:

ax- 2y =8

or, a×3 - 2×2 =8

or, 3a-4=8

or, 3a=8+4

or, a=12/3

or a=4

x+ by = 5

or, 3+b×2=5

or, 2b=5-3

or, b =2/2

or, b=1
