Basic Algebraic Equations- Solving a Single Variable

​When solving a basic algebraic problem, make sure to use the INVERSE, or OPPOSITE, operation.

Example: 8 + X = 15------- Use Subtraction!
9 - y = 22--------------Use Addition!
10X= 40-----------------Use Division!
9/X= 36-----------------Use Multiplication!

By Nicole Kantor

​Remember these important symbols when solving for the variable in an algebraic problem:

9X= letter and number RIGHT next to each other= MULTIPLICATION


9/X= Fraction- the slash always represents DIVISION

5
X= Fraction- this is always DIVISION

Multiple Choice

7 - X = 10
