# Find Three Ordered Pair Solutions 2x-y=4 2x-y=4
Solve the equation for y.
Subtract 2x from both sides of the equation.
-y=4-2x
Multiply each term in -y=4-2x by -1
Multiply each term in -y=4-2x by -1.
(-y)⋅-1=4⋅-1+(-2x)⋅-1
Multiply (-y)⋅-1.
Multiply -1 by -1.
1y=4⋅-1+(-2x)⋅-1
Multiply y by 1.
y=4⋅-1+(-2x)⋅-1
y=4⋅-1+(-2x)⋅-1
Simplify each term.
Multiply 4 by -1.
y=-4+(-2x)⋅-1
Multiply -1 by -2.
y=-4+2x
y=-4+2x
y=-4+2x
y=-4+2x
Choose any value for x that is in the domain to plug into the equation.
Choose 0 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-4+2(0)
Simplify -4+2(0).
Multiply 2 by 0.
y=-4+0
Add -4 and 0.
y=-4
y=-4
Use the x and y values to form the ordered pair.
(0,-4)
(0,-4)
Choose 1 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-4+2(1)
Simplify -4+2(1).
Multiply 2 by 1.
y=-4+2
Add -4 and 2.
y=-2
y=-2
Use the x and y values to form the ordered pair.
(1,-2)
(1,-2)
Choose 2 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-4+2(2)
Simplify -4+2(2).
Multiply 2 by 2.
y=-4+4
Add -4 and 4.
y=0
y=0
Use the x and y values to form the ordered pair.
(2,0)
(2,0)
These are three possible solutions to the equation.
(0,-4),(1,-2),(2,0)
