Writing and solving equations

Two-step equations — word problems Simply put, two-step equations — word problems are two step equations expressed using words instead of just numbers and mathematical symbols. They are just a bit more complicated than one-step equations with word problems and they demand just a bit more effort to solve.

If you are not confident in your abilities to solve two-step equations with word problems, you can go to one-step equations — word problems and practice some more before continuing with this lesson. But if you feel ready, we will show you how to solve it using this example: For how many hours did she rent the bike?

Solve linear equations step-by-step

First thing we have to do in this assignment is to find the variable and see what its connection is with the other values. The thing we do not know is the number of hours Janice rented the bike for and we have been asked to find that out.

That means the number of hours is our variable. Let us write that down as an equation. We will do that by dividing the whole equation by 4. If you want to check the result — you can.

These word problems are called two-step because you have to perform two mathematical operations in order to solve them. In this case — addition subtraction and multiplication division. To practice solving two-step equations — word problems, feel free to use the worksheets below.

Two-step equations — word problems exams for teachers Exam Name.74 CHAPTER 2 Equations, Inequalities, and Problem Solving As we explore in this section, an expression such as is not as simple as possible,because—even without replacing x by a value—we can perform the indicated addition.

A system of equations is a collection of two or more equations with the same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.
