Practice: Linear Systems Two-Variable Linear Systems 1. Solve the linear system. -2x + 3y = -18 -7x - 2y = -13 2. Solve the linear system. 2x - 3y = 9 -4r + 6y = -4 3. Solve the linear system. x + 3y = 2 -2x - 6y = -4Con! a. For problems 4 and 5: (a) Clearly identify your variables, (b) Write a system of 2 equations using your variables, (c) Solve the linear system, and (d) State your final answer, including units. 1. 500 tickets were sold for a fundraising dinner. The receipts totaled $9150. Adult tickets were $21 each and children's b. tickets were $13.50 each. How many of each type of ticket were sold? Cons a. ind 5. Two buses leave towns 536 miles apart at the same time and travel toward each other. One bus travels 14 mph faster than the other. If the buses meet in 4 hours, what is the rate of each bus? 121Three-Variable Linear Systems 6. Solve the linear system.
