Write and solve two step equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

What is the first step to solve the equation 3c + 5 = 23?

Back

Subtract 5 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation 3c = 18?

Back

Divide both sides by 3 to find the value of c.

Front

How do you represent a situation where a fixed cost is added to a variable cost?

Back

Use an equation like y = mx + b, where b is the fixed cost and mx is the variable cost.

Front

What does the variable 'h' represent in the equation 15 + 2h = 33?

Back

The variable 'h' represents the number of hours the boat was rented.

Front

How do you set up an equation for a total cost problem?

Back

Identify the fixed cost and the variable cost, then create an equation that sums them to equal the total cost.

Front

What is the solution to the equation 800 + 5x = 4000?

Back

x = 640, meaning 640 books can be printed.

Front

What does it mean to isolate a variable in an equation?

Back

To isolate a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.

Front

How do you solve the equation 20,000 - 15s = 14,700?

Back

Add 15s to both sides and then subtract 14,700 from 20,000 to find s.

Front

What is the first step to solve the equation 3c + 5 = 23?

Back

Subtract 5 from both sides to get 3c = 18.
