Algebra Practice Sheet

Introduction

Algebra is the branch of mathematics that deals with the manipulation of symbols and the rules for manipulating those symbols. Algebra is used to solve equations and to describe relationships between two or more variables.

Definitions

• Variable: A symbol (usually a letter) that stands for an unknown value.
• Equation: A mathematical statement that two expressions are equal.
• Expression: A combination of variables, numbers, and operations.

Solving Equations

The goal of solving an equation is to find the value of the variable that makes the equation true. To do this, you must isolate the variable by using the operations of addition, subtraction, multiplication, and division.

Example:

Solve for x:

2x + 3 = 7

Solution:

2x + 3 = 7 2x = 7 - 3 2x = 4 x = 4/2 x = 2

Practice Problems

1. Solve for x:

3x - 5 = 10

Answer: x = 5

1. Solve for y:

2y + 4 = 12

Answer: y = 4

1. Solve for z:

z/2 = 8

Answer: z = 16

1. Solve for w:

3w - 6 = 18

Answer: w = 8
