Solve by elimination 4x + 2y = 14 7x – 3y = -8 Step 1: Eliminate one variable Eliminate the variable y by multiplying the first equation by 3 and the second equation by 2. Solve by elimination -2x + 15y = -32 7x y = 17 Solve for the eliminated variable using either of the original equations. Solve by the elimination method: 2x + 5y = -22 10 x + 3y = 22 Step 1: Eliminate one variable To prepare for eliminating x, multiply the first equation by 5 5(2x + 5y = -22) 10x + 3y = 22ġ0x + 25y = -110 10x + 3y = 22 Subtract the equations to eliminate x. Step 2: Solve for the eliminated variable y using either of the original equations.Ħ Adding Equations 3x + 6y = 48 3(2) + 6y = 48 6 + 6y = 48 y = 7ħ Solve by elimination 6x – 3y = 3 -6x + 5y = 3 Substitution will have you substitute one equation into the other elimination will have you add or subtract the equations to eliminate a variable graphing will have you sketch both curves to visually find the points of intersection. Step 1: Eliminate y because the sum of the coefficients of y is zero.Ĥ Adding Equations 5x – 6y = -32 3x + 6y = 48 8x = 16 x = 2ĥ Adding Equations Solve by elimination: 5x – 6y = -32 3x + 6y = 48 There are three ways to solve systems of linear equations: substitution, elimination, and graphing. Subtraction Property of Equality: If a = b, then a – c = b – c.ģ Adding Equations Solve by elimination: 5x – 6y = -32 3x + 6y = 48 Addition Property of Equality: If a = b, then a + c = b + c. Book Liberty Hill Middle School Algebra IĢ Elimination Method You can use the Addition and Subtraction Properties of Equality to solve a system by the elimination method. Please see the TI-Nspire family handheld and computer software guidebooks for additional information.Presentation on theme: "Solving Systems Using Elimination"- Presentation transcript: ![]() ![]() The handheld should return which means Dan has (10) quarters and (10) dimes in his pocket. Press the key to move to the second box and input 0.25x+0.10y=3.50.Ĥ) Press to solve the system of linear equations. For the "Number of Equations" option, select "2" and for the "Variables" option, input "x,y". Press to continue.ģ) The linSolve( ) command is now copied to the Calculator application. Press to insert the Calculator application.Ģ) Press to access the Solve System of Linear Equations. If prompted to save the existing document, choose "Yes" or "No". How many quarters and dimes does Dan have in his pocket?įrom the example above, the following (2) equations can be written: x+y=20 and 0.25x+0.10y=3.50.ġ) Press to create a new document. An example system of linear equations is below:Įxample: Dan has (20) coins in his pocket and the coins total up to $3.50. More information on the latest operating system can be found at the TI-Nspire family latest software website. Texas Instruments recommends all TI-Nspire family users update the handheld and computer software to the latest operating system. ![]() To solve a system of linear equations using the TI-Nspire family products, the "Calculator" application and "Solve System of Linear Equations." template must be used.
