The Testing solutions of equations and inequalities word problems exercise formerly appeared under the 6th grade (U.S.) Math Mission and Algebra I Math Mission. It was removed on 3/18/2015. This exercise practices the skills of substituting values into expressions and verifying solutions of equations and inequalities.
Types of Problems
There is one type of problem in this exercise:
- Find which solutions satisfy: This problem describes a word problem that can be modeled with an equation or an inequality, and also provides the equation or inequality. The student is asked to verify which of the solutions in a multiple select list are valid for the situation.
This exercise is easy to get accuracy badges because values can be placed in a calculator to see if they work. The speed badges are medium because it is necessary to sometimes go through all the solutions to find which ones work.
- Solving the equation or inequality can help determine the correct answers, but is not necessarily time efficient for speed badge purposes.
- On inequalities, once a solution is found it is possible to use the direction of the inequality to provide additional solutions.
