Question

(4) 5x - 3y = 0, 3x - 5y = 16​

Answer 1

Answer:

5x-3y=0 (1)

3x-5y=16 (2)

5x-3y=0

5x=3y

x=3y/5 (3)

put the value of x in equation (2)

3x-5y= 16

3(3y/5) -5y =16

9y/5-5y=16

9y-25y/5 =16

-16y/5=16

-16y=80

y= -5

put the value of yr in equation (3)

x= 3y/5

x= 3×-5/5

x= -15/5

x= -3
