Ex. 1) The goal is to get 1x alone. To do this, multiply both sides by, which is the reciprocal of. Reduce fractions if possible. 4 1 Multiply fractions, and simplify.

Ex. 2) Subtract 5 from both sides to get the x term alone. Multiply both sides by, which is the reciprocal of. Reduce fractions if possible. Multiply fractions, and simplify.

Ex. 3) Add 4 to both sides to get 1x alone. To eliminate the fraction, multiply both sides by, which is the reciprocal of. Reduce fractions if possible. -3 1

Ex. 4) The perimeter of Mr. Mac Gregor’s garden is 64 meters. The length of the garden in 20 meters. What is the width of the garden? Write and solve an equation to answer this question! Let w = width of the rectangle The perimeter is the distance around the outside of the rectangle. P = 2(Length) + 2(width) P = 2L + 2w = 2w 2 12 m = w The width of the garden is 12 meters. 20 m w w 64 = 2(20) + 2w 64 = w

Ex. 5) Students at the rec center are taking a trip to the county fair. The cost of the trip is $52 per student. This price includes a concert ticket worth $11 and 2 passes for the rides and the game booths. If the passes are worth the same amount of money, how much does 1 pass cost? Write and solve an equation to answer this question! Let x = cost of 1 pass Total cost = cost of concert ticket + cost of 2 passes = 2x 2 $20.50 = x One pass would cost $ = x

Ex. 6) Subtract 1 = from both sides to get 1x alone. Multiply both sides by, which is the reciprocal of. Reduce fractions if possible. 4 3 Change the mixed numbers to improper fractions.
