Question

2x-y-19=0 x-3y-9=0 find the value for x and y
​

Answer 1

2x-y-19=0
2x-y=19------(1)

x-3y-9=0
x-3y=9-------(2)

multiplying equation no.1 by 3
6x-3y=57-----(3)

subtracting equation no.2 from 3
5x=48
x=48/5

put x=48/5 inequation no.2
48/5-3y=9
48-3y=45
-3y=45-48
-3y=-3
y=3/3
y=1

(x,y)=(48/5,1)
