# Find Three Ordered Pair Solutions 2x-y=7 2x-y=7
Solve the equation for y.
Subtract 2x from both sides of the equation.
-y=7-2x
Multiply each term in -y=7-2x by -1
Multiply each term in -y=7-2x by -1.
(-y)⋅-1=7⋅-1+(-2x)⋅-1
Multiply (-y)⋅-1.
Multiply -1 by -1.
1y=7⋅-1+(-2x)⋅-1
Multiply y by 1.
y=7⋅-1+(-2x)⋅-1
y=7⋅-1+(-2x)⋅-1
Simplify each term.
Multiply 7 by -1.
y=-7+(-2x)⋅-1
Multiply -1 by -2.
y=-7+2x
y=-7+2x
y=-7+2x
y=-7+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=-7+2(0)
Simplify -7+2(0).
Multiply 2 by 0.
y=-7+0
Add -7 and 0.
y=-7
y=-7
Use the x and y values to form the ordered pair.
(0,-7)
(0,-7)
Choose 1 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-7+2(1)
Simplify -7+2(1).
Multiply 2 by 1.
y=-7+2
Add -7 and 2.
y=-5
y=-5
Use the x and y values to form the ordered pair.
(1,-5)
(1,-5)
Choose 2 to substitute in for x to find the ordered pair.
Remove parentheses.
y=-7+2(2)
Simplify -7+2(2).
Multiply 2 by 2.
y=-7+4
