Solving One and Two Step Equations

Front

What is a variable in an equation?

Back

A symbol, often a letter, that represents an unknown value in an equation.

Front

What does it mean to isolate a variable?

Back

To manipulate an equation so that the variable is on one side and all other terms are on the other side.

Front

What is the first step to solve the equation 4p = 12?

Back

Divide both sides by 4 to isolate p.

Front

How do you solve the equation x - 62 = 123?

Back

Add 62 to both sides to isolate x.

Front

What is the solution to the equation 16 = p - 3?

Back

Add 3 to both sides to get p = 19.

Front

What is the first step in solving 2x + 16 = 130?

Back

Subtract 16 from both sides.

Front

What is the goal of solving two-step equations?

Back

To isolate the variable to find its value.

Front

What does it mean to combine like terms?

Back

To simplify an expression by adding or subtracting terms that have the same variable raised to the same power.

Front

What is the coefficient in the equation 3x + 5 = 20?

Back

The coefficient is 3, which is the number multiplied by the variable x.

Front

What operation would you use to solve the equation 5x = 25?

Back

Divide both sides by 5 to isolate x.
