2.4, and a sneak of 2.5Graphing Project #4

Solving Linear Equations: ax+b=c

2.4

Procedure for multi-step solving…• Combine like terms• Add the opposite to MOVE constants away

from the variable• ReMOVE the coefficient of the variable using

Multiply/divide.• GOAL: to get a +1 coeffience.• CHECK your answer.
