9-7 Solve Systems of Equations Algebraically 20. Wil paid $35 for 5 T-shirts. Some of the T-shirts cost $5 each and the rest cost $10 each. Write and solve a system of equations to represent this situation. Interpret the solution. ANSWER: x + y = 5; 5x + 10y = 35; (3, 2); Wil bought 3 shirts for $5 each and 2 shirts for $10. Solve each equation. 32. –3x – 10 = 2(2x + 2) – 7x ANSWER: no solution eSolutions Manual - Powered by Cognero Page 1
