the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.

Sensible but hard to explain
First of all, if 'x' is 3, then 'x' doesn't equal -3x+3 . You must mean y = -3x + 3.If x=3, then (-3x + 3) = -6 .The graph is the point (3, -6) .
3x+5=20 x=5 since 5x3+5=20
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4

-3x + 5 = 20 -3x = 15 x = -5
3x - 9y = 27-9y = -3x + 279y = 3x - 27y = x/3 - 3The graph is a straight line, with (slope = 3), and passing through the point (y = - 3) on the y-axis.
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
