2 -STEP EQUATIONS 7. EE. 4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. 7. EE. 4 a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.

2 -STEP EQUATION WORD PROBLEMS 7. EE. 4 Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. 7. EE. 4 a. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach.

A square has a perimeter of 40 with each side length measuring 2 x – 6. Write and solve an equation to find x.

STEPS Step 1: What is the variable (what do we not know) Step 2: What is the “answer” in the equation Step 3: Set up equation Step 4: Solve equation Step 5: Reread problem to make sure your answer makes sense

SETTING-UP THE EQUATION •

Example : A new one year membership at the YMCA costs $160. A registration fee of $28 is paid up front and the rest is paid monthly. How much do new members pay each month? Step 1: What is the variable…what do we not know? - x = monthly fee Step 2: What is the “answer” in the equation - costs $160 so =160 Step 3: What information is given that is a set amount? - +28 (paid once) Step 4: Set up equation -registration fee plus 12 times monthly cost is $160 28 + 12 x = 160 Step 5: Solve equation Step 6: Reread problem to make sure your answer makes sense
