You solved systems of equations by graphing. • Solve systems of equations by using substitution. • Solve real-world problems involving systems of equations by using substitution. Then/Now
3 METHODS TO SOLVE A SYSTEM OF EQUATIONS BY GRAPHING (Lesson 6-1) √ BY SUBSTITUTION (Lesson 6-2) BY ELIMINATION – a. with Addition and Subtraction (Lesson 6-3) b. with Multiplication (Lesson 6-4)
Use substitution to solve the system of equations. 1. What is the solution to the system of equationsy = 2x + 1 and y = –x – 2? 5-Minute Check 4
2. Adult tickets to a play cost $5 and student tickets cost $4. On Saturday, the adults that paid accounted for seven more than twice the number of students that paid. The income from ticket sales was $455. How many students paid? 5-Minute Check 6
Solve and then Substitute Use substitution to solve the system of equations.4x + 5y = 11 y – 3x = -13 Step 1 Solve the first equation for ysince the coefficient is -1. Example 2
Use substitution to solve the system of equations.3x – y = –12–4x + 2y = 20 Example 2
No Solution or Infinitely Many Solutions Use substitution to solve the system of equations.2x + 2y = 8x + y = –2 Solve the second equation for y. x + y = –2 Second equation x + y– x = –2 – xSubtract x from each side. y = –2 – x Simplify. Substitute –2 – x for y in the first equation. 2x + 2y = 8 First equation 2x + 2(–2 – x) = 8 y = –2 – x Example 3
No Solution or Infinitely Many Solutions 2x – 4 – 2x = 8 Distributive Property –4 = 8Simplify. Answer: no solution The statement –4 = 8 is false. This means that there are no solutions of the system of equations. If a system results in a false sentence such as -4 = 8, then the system has no solution. The equations represent parallel lines. Example 3
Use substitution to solve the system of equations.3x + y = -56x + 2y = 10 If a system results in a true sentence, then the system has infinitely many solutions. This happens when 2 equations are the same line. Example 1
Write and Solve a System of Equations NATURE CENTER A nature center charges $35.25 for a yearly membership and $6.25 for a single admission. Last week it sold a combined total of 50 yearly memberships and single admissions for $660.50. How many memberships and how many single admissions were sold? Let x = the number of yearly memberships, and let y = the number of single admissions. So, the two equations are x + y = 50 and35.25x + 6.25y = 660.50. Example 4
Write and Solve a System of Equations Step 1 Solve the first equation for x. x + y = 50 First equation x + y– y = 50 – ySubtract y from each side. x = 50 – y Simplify. Step 2 Substitute 50 – y for x in the second equation. 35.25x + 6.25y = 660.50 Second equation 35.25(50 – y) + 6.25y = 660.50 Substitute 50 – y for x. Example 4
Write and Solve a System of Equations 1762.50 – 35.25y + 6.25y = 660.50 Distributive Property 1762.50 – 29y = 660.50 Combine like terms. –29y = –1102 Subtract 1762.50 from each side. y = 38 Divide each side by –29. Example 4
Write and Solve a System of Equations Step 3 Substitute 38 for y in either equation to find x. x + y = 50 First equation x + 38 = 50 Substitute 38 for y. x = 12Subtract 38 from each side. Answer: The nature center sold 12 yearly memberships and 38 single admissions. Example 4
