1.6 – Translating Problems into Equations

Words to Equations:• Read the problem carefully.– Decide what the unknowns are– Decide what the facts are

• Choose a variable and represent the unknowns.– Choose a variable for one unknown– Write an expression for the other unknown using

the variable• Reread the problem and write an equation.– Use the other fact from the problem to write an

equation

Example #1• A wooden rod 60 in. long is sawed into two

pieces. One piece is 4 in. longer than the other.

Example #2• Lyn has twice as much money as Jo. Together

they have $63. How much money does each have?

Example #3• The length of a rectangle is one unit more

than its width. If the area is 30 square units, find the dimensions of the rectangle.

Reflection:• What is a “let statement?”

• What are the steps used to set up a problem?

• What do you do when you have an unknown in a problem?
