Math Missions: 7th grade (U.S.) Math MissionAlgebra basics Math Mission, Mathematics I Math Mission, Algebra I Math Mission, Mathematics II Math Mission, Algebra II Math Mission, Mathematics III Math Mission
Types of Problems: 2

The Linear equation word problems exercise appears under the 7th grade (U.S.) Math MissionAlgebra basics Math Mission, Mathematics I Math Mission, Algebra I Math Mission, Mathematics II Math Mission, Algebra II Math Mission and Mathematics III Math Mission. This exercise helps to set up and solve linear equations.

## Types of Problems

There are two types of problems in this exercise:

1. Write an equation and find solution: This problem provides a word problem that can be modeled by a linear equation. The student is asked to find an equation that models the situation and find the solution to that equation.
2. Just write the equation: This word problem only requires the student to write an equation. There is not a need to solve and get the final answer.

## Strategies

Experience and comfort with translating between English and mathematics can help to ensure accuracy on this exercise.

1. The problems will accept any equation, so the equation created does not need to conform to any simplification standards.
2. Since any equation works and students have to solve the first type of problem, it is recommended to just solve the problem and use the equation $x=\text{whatever the answer is}$.
3. It is not necessary to solve the second type of problem, so there it is recommended to just write the equation as it is being read.

## Real-life Applications

1. Linear equations can be used to solve many problems, both everyday and technically specific.
2. Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
3. Equations show up in nearly every science or business class one is ever in.
4. Computers are also equation solvers. Computers were originally invented to solve equations over and over again instead of humans doing the calculations.
