6-5 Applying Systems of Linear Equations

The solution is (2, 3).

9. 5x + 8y = 1

−2x + 8y = −6

SOLUTION:

The coefficients for y are the same. Solve the system by elimination using subtraction.

Now, substitute 1 for x in either equation to find the value of y.

The solution is

12. FINANCIAL LITERACY For a Future Teachers of America fundraiser, Denzell sold food as shown in the table.

He sold 11 more subs than pizzas and earned a total of $233. Write and solve a system of equations to represent this

situation. Then describe what the solution means.

SOLUTION:

Let s represent the number of subs sold and p represent the number of pizzas sold.

3s + 5p = 233; s = p + 11

Solve through substitution.

Now, substitute 25 for p in either equation to find the value of s.
