3. Using commutative property of addition, place like terms adja­ cent to each other: –2x + –7 + –6. 4. Combine like terms to yield the simplified answer: –2x – 13. Sometimes, you are given a negative sign, but no number has to be distributed over the parentheses. In this case, you can use the identity property of mul­ tiplication to place a 1 in front of the parentheses so that you can distribute a –1. Remember that any number multiplied by 1 has the same value. Chapter 3: Simplifying Expressions 35 Example 10: Simplify the following expression: –17 – (x – 12) In this expression, x – 12 is being subtracted from –17.

Circle the leading keyword and indicate the TO that it defines; box the turnaround word. add (the difference between four and twice a number) to (the sum of five and the number) 22 CliffsQuickReview Math Word Problems 4. Translate each underlined expression individually. a. In the first underlined expression, underline the terms before and after AND that corresponds to the leading keyword DIF­ FERENCE BETWEEN. the difference between four and twice a number b. Because a keyword, TWICE, appears in the second underlined expression, put parenthesis around that expression.

2. Translate the words into the correct symbols. 2(3 – x) = 4x 3. Distribute and combine like terms. 6 – 2x = 4x 4. Move the variables to the left side of the equation. 6 – 2x – 4x = 4x –4x 5. Simplify each side of the equation. 6 – 6x = 0 Note: The right side of the equation is now 0. The equation must have expressions on either side of the equality sign to be solvable. You cannot just leave the right side of the equation blank. 0 is the expression on the right side of the equation. 6. Move the constant to the right side of the equation.
