When you solve an equation containing like terms, combine them first before continuing to solve the equation. To solve 3a + 2a + 4 = 14, proceed as follows. 3a + 2a + 4¬= 14 5a + 4¬= 14 Combine like terms. 5a + 4 4 = 14 4 – – 5a = 10 = 2 a Solve each equation. Then locate the solution on the number line below. Place the letter corresponding to the answer on the line at the right of the exercise. A letter may be used more than once. 1. 3x + 4x + 3 = -39 ________ 2 + 5x = 12 ________ 2. –3x – 3. 4x + 7x = 1 ________ –5 – + 6x 2 = 20 ________ 4. – + 1.2 + 1.2x = 4.8 ________ 5. –2.4x 6. (6 = ________ x) – –1 7. 1 ________ 8. 7x + (–2x) + = 42 ________ x 9. (5x + 5x) = ________ –20 TWO–STEP EQUATIONS TWO–STEP EQUATIONS: Work Backwards 1) Find the VARIABLE.
