1. 2-6 solving Two-Step Equations What You’ll Learn To solve two step equations To solve two step equations

2. Equations: Two-Step Two-step equations require students to perform two operations before solving the equation. Two-step equations require students to perform two operations before solving the equation. For example, the equation 3x - 3 = 18 requires adding 3 to both sides of the equation and dividing both sides of the equation by 3. For example, the equation 3x - 3 = 18 requires adding 3 to both sides of the equation and dividing both sides of the equation by 3.

3. Example 1: Find the value of n in the equation 6n - 9 = 9 Step 1: In the equation, solve for the value of n by first getting n alone. Add +9 to both sides of the equation. Step 2: Divide both sides of the equation by 6.

4. Example 2: Solve for t. t/8 + 3 = 12 Step 1: To get the variable alone, subtract 3 from both sides of the equation. Step 1: To get the variable alone, subtract 3 from both sides of the equation. Step 2: Isolate the 't' by multiplying by the reciprocal of 1/8, which is 8/1. Step 2: Isolate the 't' by multiplying by the reciprocal of 1/8, which is 8/1.

5. Write and solve the equation The computer club sells 50 more than 3 times as many pins as the chess club. The computer club sell 134 pins. How many pins did the chess club sell? The computer club sells 50 more than 3 times as many pins as the chess club. The computer club sell 134 pins. How many pins did the chess club sell? Assign a variable Assign a variable P = pins sold by the chess club P = pins sold by the chess club Set up equation Set up equation 50 + 3p = 134 50 + 3p = 134 Solve equation Solve equation P = 28 pins sold by the chess club P = 28 pins sold by the chess club
