  1. Negative Coefficient Variable Equations

  2. BOTH Is this a “positive 5” or “plus 5”? 5 – 2x = 14 Negative Coefficient Equations +

  3. Negative Coefficient Equations • HINT: If you don’t see a negative or positive sign in front of a number it is always positive. 5 +

  4. BOTH Is this a “negative 7x” or “minus 7x”? 2 –7x = 10 Negative Coefficient Equations

  5. Negative Coefficient Equations • HINT: The sign in front of the numberBELONGS TO THE NUMBER! –7

  6. Negative Coefficient Equations What’s the coefficient? The coefficient is the number before the variable.

  7. Negative Coefficient Equations Name theCoefficient 3x + 4 = 3 3 5 – 7x = 2 – 7 8 – x = 10 – 1 What does –represent? It represents -1.

  8. Negative Coefficient Equations Name the Coefficient - x + 8 = 5 -1 8 – 6x = 4 – 6 4 – x = 10 – 1

  9. Negative Coefficient Equations 1)GOAL: Get the variable on one side of the equation. 2) You always perform the same operation to both sides of an equation. 3) To undo an operation you perform its opposite operation to both sides of the equation. 4) It is easier if you undo addition or subtraction before you undo multiplication or division.

  10. Negative Coefficient Equations I will show you how to solve this problem 2 different ways.

  15. #17 Negative Coefficient Equations 1)Get the variable alone, even if the coefficient is negative. -3 -3 • 3 - 2x = 11 - 2x = 8 __ __ -2 -2 2)Subtract 3 from both sides. 3) +3 and -3 cancel out x = -4 4) Divide both sides by - 2 3 - 2(-4) = 11 5) -2 divided by –2 cancel out 3+ 8 = 11 6) Show your check. 11 = 11 7) Finish your check.
