<p>Module: Solving Linear Equations Name: Lesson: Solving Equations and Formulas Date: Period:</p><p>Student Notes:</p><p>Define: 1. Equation - </p><p>Ex: x = yz What do x, y, and z stand for? ______</p><p>2. Formula - </p><p>Ex: A = lw What do the A, l, and w stand for? A = ______, l = ______, and w = ______</p><p>What does it mean to solve for a variable?</p><p>Ex: When you solve for x, the equation should look like x = ____ .</p><p>Use the ______to help you solve these problems.</p><p>Ex: Solve -5x + y = -56 for x.</p><p>Ask yourself, “What is being done to x?” DO UNDO First, it is being ______• (-5) -y Then, ______+y ÷ (-5)</p><p>Solve: -5x + y = -56 for x.</p><p>What do you like better about solving formulas for a given variable than solving equations in one variable? </p><p>Solve: 2x - 4y = 7 for x. DO UNDO</p><p>Solve: a(y + 1) = b for y. DO UNDO</p><p>Solve: 3ax - b = d - 4cx Steps: First move all x terms to one side. Then use the distributive property backwards. Solve for x.</p><p>Try a few on your own: 1.2W Solve P = , for W. DO UNDO H 2</p><p>Solve P = 2l + 2w for l. DO UNDO</p><p>Solve 4x - 3m = 2mx - 5 for x. DO UNDO</p>
