The table shows four equations. If x=3, which equation has a y-value different from the other three equations?

• Equation 1

• Equation 2

• Equation 3

• Equation 4

• 4

• 1

• 12

• 5

Which of these forms has one solution?

• y=5

• 5=2

• 2=2

• No solutions

• 1 solution

• 2 solutions

• infinite number of solutions

Which of these is a correct statement?

• Because if you add -22x to both sides of the equation and simplify, you get -18=-18

• Because if you add -22x to both sides of the equation and simplify, you get 0=-18

• Because if you subtract -22x to both sides of the equation and simplify, you get -18=-18

• Because if you subtract -22x to both sides of the equation and simplify, you get 0=-18
