Hello my wonderful Grade 5 superstar! π
I'm Kashef and today we're learning to Solve One-Step Equations! These are simple equations with a variable (like x) and just one operation. We'll use inverse operations to find the mystery number. It's like solving a fun puzzle! Ready? Letβs balance some equations! π
π§ What is a One-Step Equation?
An equation is a math sentence that says two things are equal. It has a variable (x) and we solve to find its value.
π Inverse Operations (The Magic Key)
To solve, do the opposite operation on both sides to keep it balanced!
Addition β Subtraction
Multiplication β Division
βοΈ Step-by-Step Examples
Example 1: x + 7 = 15
x = 15 - 7 = 8
Example 2: x - 4 = 9
x = 9 + 4 = 13
Example 3: 6x = 42
x = 42 Γ· 6 = 7
π― Letβs Solve Some Equations!
1. x + 9 = 16
2. x - 5 = 12
3. 5x = 35
π Real-Life Equation Problems
Problem 1: You have some stickers. After giving 8 to your friend, you have 15 left. How many did you start with? (Let x = starting stickers)
Problem 2: 6 friends share some candies equally and each gets 9. How many candies were there? (Let n = total candies)
