Consider the system: Line 1: x - y = 9
Line 2: 3x + 3y = 3
The ordered pair (3, -6) is a solution to:
Line 1
Line 2
The System of Equations

Line 1

Step-by-step explanation:

Since x=3 and y=-6, just plug those two values in both of the equations.

Line1: (3)-(-6)=9    This would be the answer

Line2: 3(3)+3(-6) = -9  This is the incorrect answer because it should 3

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
