Understanding Equations with Two Unknown Variables

What is an equation?

• A statement where two expressions have different values

• A statement where two expressions have the same value

• A statement with no variables

• A statement with only numbers

How do you find the value of the second variable in an equation with two unknowns?

• By adding random numbers

• By using a calculator

• By creating a table and using inverse operations

• By guessing

What happens when you introduce decimals into equations with two unknown variables?

• The number of solutions becomes infinite

• The equation becomes a numerical equation

• The number of solutions becomes limited

• The equation becomes unsolvable

In algebra, what does it mean when two variables are placed next to each other without an operation sign?

• They are divided

• They are multiplied

• They are subtracted

• They are added together

What is the inverse operation of multiplication?

• Subtraction

• Addition

• Multiplication

• Division

If a times b equals 6, and a is 2, what is b?

• b = 5

• b = 4

• b = 3

• b = 2

What is the first step in solving a complex equation with multiple variables?

• Guess the values of the variables

• Create a table to organize potential values

• Use a calculator to find the answer

• Ignore the variables

What is the result of 2x + y = 18 when x = 1?

• y = 14

• y = 16
