Question. . .
simplifyWhat does mean?
Easy. It means make fewer things for youreyeballs to look at. Or fewer things foryour brain to have to focus on.
Example: 1 + 2 + 3 + 4 or 10
Which is easier to look at or to focus on?
simplified!
simplifyIn math, means . . .
combine like terms.
Example: y = 8x – 2x + 10 +x - 12
Add this to your foldable, step 1.and follow along.
simplifyingSo is that all there is to ?
Well no. There’s more. There’s actuallya step that comes before combining like terms . . . .
All you gottado is ? combine like terms
distribute.
Add this to your foldable, step 1.
Do you recallwhat it means to ?distribute
It means multiply (or divide) everythingINSIDE the group by what’s OUTSIDE the group.
Example: y = -3(2x – 4)
How to solve (for y) like a
Step 2: ISOLATE the “y” term.
ROCKSTAR
Step 1: Simplify- distribute- combine like terms
Write this down on your foldable.
That’s right! ALONE.ALONE means ALONE. No friends on the same side of the fence. None. Zippo. Nada. Zilch.
Step 2: ISOLATE the y term.
Examples: y – 3x = 19 y + 2x = 3x - 10

ROCKSTAR
Step 1: Simplify- distribute- combine like terms
Step 3: Divide by the y coefficient.
Write this down on your foldable.
coefficientWHAT. Is a ?
Simple. A COEFFICIENT is a numberthat is multiplied (or divided) by a variable.
Example: 21y or - ½ y
coefficient coefficient
Step 3: Divide by the y coefficient.
Examples:-6y = 18x - 36 or 3y = 9x + 5
