Answer 1

Answer:

these are simply calculation

Answer 2

Step-by-step explanation:

9. 2(x-3) + 3(y-5)=0

2x-6+3y-15= 0

2x+3y-21= 0

2x+3y= 21-----------------(1)

5(x-1)+4(y-4)=0

5x-5+4y-16=0

5x+4y-21=0

5x+4y=21------------------(2)

From (1) and(2) we get,

2x+3y=5x+4y. ATQ

3y-4y=5x-2x

-1y=3x

we get,

3x=21

x=7

-1y=21

y=-21
