Juanita and Jamal are solving the system 2x y = 6 and 2x + y = 10. Who is correct? Explain your reasoning. Juanita 2x y = 6 _____________ ()2x + y = 10 0 = 4 The statement 0 = 4 is never true, so there is no solution. Jamal 2x y = 6 2x y = 6 ____________ (+)2x + y = 10 2(4) y = 6 4x = 16 8 y = 6 x = 4 y = 2 The solution is (4, 2).

In order to practice at home, Tadeo purchased a basketball and a volleyball that cost a total of $67, not including tax. If the price of the basketball b is $4 more than twice the cost of the volleyball v which system of linear equations could be used to determine the price of each ball? A b + v = 67 C b + v = 4 b = 2v - 4 b = 2v - 67 B b + v = 67 D b + v = 4 b = 2v + 4 b = 2v + 67
