In order to find the solution, you need to isolate C.įirst step – place the values of A and B: (B + C)/2 = 2A – B In addition, while it is tempting to remove the parentheses, in this case, since the values of two of three variables are given, it is better to place the values first, and only then to check whether there are any parentheses left to remove. In order to solve this problem correctly, you need to remember the order of operations: This step significantly simplifies the expression and makes it much easier to continue the solution according to the order of operations. To save time, it is usually recommended to begin by placing the values of the known variables. Oftentimes you will be given an expression consisting of multiple variables however, you will also be given the values of all the variables but one.

Solving and interpreting linear equations-either a single equation or a system of two equations.Simplifying expressions while applying the order of operations principles.In these questions, you will need to do one of the following: The most common questions that comprise this section are: Evaluating Algebraic Expressions Question Format/Instructions In addition, you should be familiar with elementary algebra and have a basic command of writing, interpreting, and solving algebraic expressions such as linear and quadratic equations.
