Negative Coefficient Variable Equations

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

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

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

Negative Coefficient Equations HINT: The sign in front of the number BELONGS TO THE NUMBER! –7

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

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

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

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.
