Question

1. what does \pair of values\ mean in a two - variable equation? a) a solution that does not make the equation true b) two numbers that represent values for two variables c) an equation with only one variable d) an equation that has infinitely many solutions 4. when is a number called a \solution\ of an equation? a) when it makes the equation false b) when it has no relation to the equation c) when it makes the equation true d) when the equation has two variables 5. what are \equivalent equations\? a) equations that look the same but have different solutions b) equations that have exactly the same solutions c) equations with two variables d) equations that have no solution

Explanation:

• For question 3, a pair of values in a two - variable equation represents two numbers for the two variables.
• For question 4, a number is a solution of an equation when it makes the equation true.
• For question 5, equivalent equations have exactly the same solutions.

Answer:

1. b) Two numbers that represent values for two variables
2. c) When it makes the equation true
3. b) Equations that have exactly the same solutions
