Question

solve the following pair of linear equations by the substition method.3×-ʏ=3
9×-3ʏ=9 ​

Answer 1

Step-by-step explanation:

3x-y=3,..........(i)

9x-3y=9.........(ii)

from equ.No (i)y=3x-3 ...(iii)

substituting this values of u in equ. (ii)

9x-3 (3x-3)=9

9=9

Or,

hence , x and y both have infinity many solution
