x-2y= -9
3x+y=1

Answer 1

find determinant first....

Answer 2

yeaa

Answer 3

lol "yea" is not a determinant..i said did u calculate the determinant. you know how to do it?

Answer 4

ok fine see i will teach you.
cramer rule says
x = Dx / D
y = Dy / D
first you want to find D

so your D=1*1 - 2*3 = 1 - 6 = -5
