Instructions on how to do Algebra Equations

1. Understanding Basics:

● Algebra is like a secret code language for numbers.
● Instead of just working with numbers, we use letters (like x, y, a, b) to represent
unknown values.
● Equations are like balanced seesaws - whatever you do to one side, you gotta do
to the other to keep it balanced.

2. Solving Equations:

● Goal: To find the value of the unknown variable (usually 'x').
● We use different operations like addition, subtraction, multiplication, and division
to solve equations.

3. Steps to Solve:

a. Simplify: Combine like terms and simplify both sides of the equation if possible.

b. Isolate the Variable:

● Undo operations in reverse order.
● Example: If there's addition, subtract. If there's multiplication, divide.

c. Keep it Balanced:

● Whatever you do to one side, do the same thing to the other side to keep the
equation balanced.

4. Common Mistakes to Avoid:

a. Forgetting the Balance:

● Always perform the same operation on both sides of the equation.
● If you add 5 to one side, you gotta add 5 to the other side too!

b. Rushing Through Steps:

● Take your time to simplify and isolate the variable correctly. Rushing can lead to
errors.

c. Misunderstanding Negative Numbers:
