SECTION 5.2 SOLVING EQUATIONS WITH VARIABLES ON EACH SIDE
OBJECTIVES Solve equations with variables on each side Solve equations that involve grouping symbols
NOTES Equations with Variables on Each Side To solve equations with variables on each side, use the ____________ or ____________ Property of Equality to write an ____________ equation with the variables on one side Then ___________ the equation
EXAMPLES 1. 7x = 5x x – 2 = x + 4
EXAMPLES 3. 2x + 3 = 3x – = p – 49
WORD PROBLEM PRACTICE 1. A personal trainer charges a one time fee of $60 plus $2 for each individual session. A new fitness club charges a yearly fee of $450 plus $10 for each session with a personal trainer. Write and solve an equation to determine for what number of sessions will the costs be equal.
WORD PROBLEM PRACTICE 2. Red Bird Cruises charges $85 per day plus a one- time fee of $75 for taxes and gratuities. King Cruises charges $100 per day plus a fee of $30. Write and solve an equation to determine for what number of days the charge for the cruises will be the same.
