Question

What is the solution of this system of linear equations? 3y = x + 6 y – x = 3

Answer 1

Y = -1/3x -2 this is the correct Answer

Answer 2

Hello :
3y = x + 6 ...(1)
y – x = 3...(2)
by (2) : y = x+3...(*)
subsct in (1) :
3(x+3) = x+6
3x-x= -9+6
2x= -3
x=-3/2
subsct in (*) : y =-3/2 +3 =3/2
