Question

The system of linear equations x = 3y + 5 and 9y = 3x - 15 is

Answer 1

x - 3y =5


3x-9y=15

i. e x-3y =5


The given system of equations has infinitely many solutions

Answer 2

x=3y+5. _(1)

9y=3x-15
3(x-5)=9y
x-5=9y/3
x-5=3y
x=3y+5. _(2)

As both equation are equal thus there are infinite solution
