4.5 & 4.6 Notes LEQ: How do we solve multistep equations with variables on both sides?
***** To solve equations with more than one operation, called ____multistep equations___, undo operations by __using the correct order of steps__. • Examples: 1) 7 m - 17 = 60 2) 3) 4)
Application: 7) Susan had a $10 coupon for the purchase of any item. She bought a coat that was on sale for ½ its original price. After using the coupon, Susan paid $125 for the coat. What was the original price of the coat?
8) 8 less than two-thirds of a number equals 4. Find the number.
9) Consecutive integer problems: • Consecutive integers are integers in counting order, such as_1,2,3 or 101,100,99__ • Name 3 consecutive even integers _______ These are how far apart? ______ • Name 3 consecutive odd integers ________ These are how far apart? _____
In general if n represents an integer, • the next integer is _n+1_, the following integer is _n+2__ • In general if n represents an (even) integer, • the next even integer is __n+2___, the following even is _n+4_____ • the next odd integer is _n+1___ , the following odd is _n+3__ *If n is an odd, the next evens are n+1 and n+3 while the next odds are n+2 and n+4
*** To solve equations with variables on each side, first use the Addition or Subtraction Properties to get all the __variables on one side and all the ___Constants_ on the other side.
Ex1) -2 + 10 p = 8 p - 1 Ex 2)
**** If there are parenthesis first use the ________________________________. Ex 3) 4 ( 2r – 8 ) = 1/7 (49 r + 70) Ex 4) 2 ( x – 1 ) = 3 ( - 2 x – 4 ) + 8
*** Some equations may have ____Distributive Property. Ex 5 ) 2m + 5 = 5 ( m – 7) - 3m
