Line 1 Line 2 Line 3 −2𝑥 + 13 − 8𝑥 = −17 6𝑥 + 13 = −17 6𝑥 = −30 𝑚 = −5 At which line does the mistake first appear? A B C D Line 1 Line 2 Line 3 The equation was solved correctly. 2𝑥−1 5 = −7 8. A merchant is selling wind chimes from a booth at a flea market. He rents his space for $125 per day. The profit from each wind chime sold is $12. His goal is to make $3500 in a five-day workweek. Which equation represents how many chimes he needs to sell in a week to meet his goal? F 12𝑐 − 625 = 3500 G 5(12𝑐) − 125 = 3500 H 5(12𝑐 + 125) = 3500 J 5(12𝑐 − 125) = 3500 Skill Review: I can combine like terms I can solve multi-step equations I can use the distributive property I can solve simple inequalities I can translate words into math 1. 2x + 4 - 7y + 9y - 5x -10 2. 3y - 7 = 14 3. 3(9x + 2) 4. a.) 7y > 21 b.) -7y > 21 5.
