Question

if (1,2) and (0,3)
ax -by =3
find the value of a and b??​

Answer 1

Answer:

The value of a is 1 and b is -1.

Step-by-step explanation:

If (1,2) then equation becomes,

a -2b = 3 ...... Equation 1

If (0,3) then equation becomes,

-3b = 3

b = 3/(-3)

b = -1

Substituting b= -1 in equation 1, we get,

a -2(-1) = 3

a + 2 = 3

a = 3 - 2

a = 1
