To solve lance’s equation, 2(x + 10) = 60, first a.subtract 10 from both sides b.multiply both sides by 2 c.divide both sides by 2 d.add 10 to both sides then a.subtract 10 from both sides b.add 10 to both sides c.multiply both sides by 2 d.divide both sides by 2 solve lance's equation, 2(x + 10) = 60, for x. according to his model, the length of the rectangle is a. 10 cm b. 43 cm c. 15 cm d. 20 cm to solve olivia’s equation, 2x + 20 = 60, first a.subtract 20 from both sides b.multiply both sides by 2 c.divide both sides by 2 d.add 20 to both sides then a.multiply both sides by 2 b.add 20 to both sides c.subtract 20 from both sides d.divide both sides by 2 solve olivia’s equation, 2x + 20 = 60, for x. according to her model, the length of the rectangle is a. 30 cm b. 2 cm c. 20 cm d. 15 cm the two equations with different solution steps lead to a. the same b. different answer(s), because 2(x + 10) = 60 and 2x + 20 = 60 a. are not b. are equivalent by the distributive property.
