Question

2x-y-3=0; , 4x-y-5=0

Answer 1

Answer:

Step-by-step explanation:

2x -y -3 =0

4x -y -5 =0

using Cramer's rule

     x            y              1

-1           -3             2         -1

-1           -5             4         -1

x / [(-1)(-5) - (-1)(-3)]   =  y / [(-3)(4) - (-5)(2)]   =   1 / [2(-1) - (-1)(4)]

x / [2]  =  y / [-2]  =  1 / [2]

on solving we get

x=1 and y =-1
