Solving Equations with Brackets on Both Sides

🧮 Example: Solve: 2(x + 3) = 3(x - 1) --- ✏️ Step 1: Expand Both Sides Use the distributive property: Left side: 2(x + 3) = 2x + 6 Right side: 3(x - 1) = 3x - 3 Now your equation becomes: 2x + 6 = 3x - 3 --- ✏️ Step 2: Move Variables to One Side Subtract 2x from both sides: 2x - 2x + 6 = 3x - 2x - 3   6 = x - 3 --- ✏️ Step 3: Solve for x Add 3 to both sides: 6 + 3 = x - 3 + 3   9 = x --- ✅ Final Answer: x = 9 --- 💡 Quick Tip: 👉 Always expand brackets first 👉 Move all variable terms to one side 👉 Move numbers to the opposite side 👉 Solve carefully, step by step! --- 🔗 Follow for More Lessons: 🌐 Website: www.easymathsguid.com.ng 📘 Blog: easymathsteps.blogspot.com ---

Solving Equations with Fractions on Both Sides

🧮 Example: Solve: (2x/3) − (1/6) = (x/2) + (1/3) --- 🔍 Step 1: Identify the Denominators The denominators are: 3, 6, 2, and 3 To simplify, we eliminate the fractions by multiplying all terms by the Least Common Multiple (LCM) of these numbers. --- ✏️ Step 2: Find the LCM Let’s list a few multiples: Multiples of 2: 2, 4, 6, 8... Multiples of 3: 3, 6, 9... Multiples of 6: 6, 12, 18... ✅ The smallest common multiple is 6 So the LCM = 6 --- ✏️ Step 3: Multiply Every Term by 6 Now apply this to the equation: 6 × (2x/3) − 6 × (1/6) = 6 × (x/2) + 6 × (1/3) Now simplify: 6 × (2x/3) = 4x 6 × (1/6) = 1 6 × (x/2) = 3x 6 × (1/3) = 2 Now rewrite the new equation: 4x − 1 = 3x + 2 --- ✏️ Step 4: Solve the New Equation Now solve like a regular linear equation: 4x − 1 = 3x + 2 Subtract 3x from both sides: x − 1 = 2 Add 1 to both sides: x = 3 --- ✅ Final Answer: x = 3 --- 💡 Quick Tip: When dealing with equations that include fractions: Always begin by finding the LCM of all denominators. Multiply eve...

Solving Word Problems Involving Fractions in Equations

This lesson shows how to solve real-world problems where fractions are involved in the equation. It builds directly from Lesson 12 on dividing fractions. --- 🔍 Steps to Solve: 1. Read the word problem carefully. 2. Let the unknown number be x. 3. Translate the words into a fraction-based equation. 4. Solve by multiplying by the reciprocal or using the LCM method. 5. State your final answer clearly. --- 📘 Example 1: Problem: One-third of a number is 9. What is the number? Solution: Let the number be x. (1/3) × x = 9 Multiply both sides by 3: x = 9 × 3 = 27 ✅ Final Answer: 27 --- 📘 Example 2: Problem: Half a number minus 2 equals 3. Find the number. Solution: (1/2) × x - 2 = 3 Add 2 to both sides: (1/2) × x = 5 Multiply both sides by 2: x = 10 ✅ Final Answer: 10 --- 📘 Example 3: Problem: Two-thirds of a number equals 16. What is the number? Solution: (2/3) × x = 16 Multiply both sides by 3/2: x = 16 × (3/2) = 48/2 = 24 ✅ Final Answer: 24 --- 📝 Practice Questions: 1. One-fourth of a ...
