Card 1Solving simple equations

Solve: x + 3 = 9

Answer

Step 1: Subtract 3 from both sides. x + 3 - 3 = 9 - 3 Step 2: Simplify. x = 6 Answer: x = 6

Card 2Solving simple equations

Solve: x - 5 = 8

Answer

Step 1: Add 5 to both sides. x - 5 + 5 = 8 + 5 Step 2: Simplify. x = 13 Answer: x = 13

Card 3Solving simple equations

Solve: 3x = 12

Answer

Step 1: Divide both sides by 3. 3x/3 = 12/3 Step 2: Simplify. x = 4 Answer: x = 4

Card 4Solving simple equations

Solve: x/9 = 2

Answer

Step 1: Multiply both sides by 9. (x/9) × 9 = 2 × 9 Step 2: Simplify. x = 18 Answer: x = 18

Card 5Solving simple equations

Solve: x + 2 = 6

Answer

Step 1: Subtract 2 from both sides. x + 2 - 2 = 6 - 2 Step 2: Simplify. x = 4 Answer: x = 4

Card 6Two-step equations

Solve: 2x + 5 = 11

Answer

Step 1: Subtract 5 from both sides. 2x + 5 - 5 = 11 - 5 2x = 6 Step 2: Divide both sides by 2. 2x/2 = 6/2 x = 3 Answer: x = 3

Card 7Two-step equations

Solve: x/3 - 8 = 10

Answer

Step 1: Add 8 to both sides. x/3 - 8 + 8 = 10 + 8 x/3 = 18 Step 2: Multiply both sides by 3. (x/3) × 3 = 18 × 3 x = 54 Answer: x = 54

Card 8Transposition rules

Why does transposing a positive term change its sign?

Answer

Transposing is a shortcut for keeping an equation balanced. A positive term moved to the other side becomes negative. Example: x + 3 = 6 Move +3 to the other side: x = 6 - 3 x = 3 The sign changes
