Let’s go step by step with solving Algebra 1 equations.

Step 1: Solving One-Step Equations

A one-step equation means you only need one operation (addition, subtraction, multiplication, or division) to solve for the variable.

Example 1: Addition/Subtraction

Solve for x:
x + 5 = 12

Solution:

• Subtract 5 from both sides:
  x = 12 – 5
  x = 7

Example 2: Multiplication/Division

Solve for y:
3y = 15

Solution:

• Divide both sides by 3:
  y = 15 ÷ 3
  y = 5

Step 2: Solving Two-Step Equations

A two-step equation means you need two operations to isolate the variable.

Example 1: Two Operations

Solve for x:
2x + 3 = 11

Solution:

1. Subtract 3 from both sides:
   2x = 8
2. Divide both sides by 2:
   x = 4

Example 2: Another Two-Step Equation

Solve for y:
5y – 7 = 18

Solution:

Simple Algebra Worksheet:

1. Add 7 to both sides:
   5y = 25
2. Divide both sides by 5:
   y = 5
