1. 8x+6y= 16
y = 4
8x+6(4) = 16
8x + 24 =16
8x = -8
x
= -1
(-1,4)
3. -x - 4y = 20
y = -6x + 18
-X-4 (-6x+18)=20
-X +24 x - 72=20
23x - 72=20

Page 2: Advanced Substitution Practice and Special Cases

This page continues with more substitution practice problems for algebra multiplication and introduces special cases in linear systems.

Problems 7-11 on this page present more challenging scenarios, including:

Systems with no solutions
Systems with infinite solutions
Systems requiring more complex algebraic manipulation

Example: Problem 8 demonstrates a system with infinite solutions: y = 3x - 6 and -3x + y = -6. The solution process shows that these equations are equivalent, resulting in infinite solutions.

Highlight: The inclusion of special cases (no solution and infinite solutions) helps students understand that not all linear systems have a unique solution.

The page maintains the step-by-step solution format, providing detailed workings for each problem. This approach allows students to follow the reasoning and calculations closely, reinforcing their understanding of the substitution method.

Definition: Special cases in linear systems:

No solution: When the equations represent parallel lines that never intersect

Infinite solutions: When the equations represent the same line

The problems on this page serve as an excellent substitution worksheet with answers PDF, offering a comprehensive practice set for students to hone their skills in solving linear systems by substitution.

Page 1: Substitution Practice Problems

This page contains six substitution practice problems for algebra with solutions. Each problem demonstrates the process of solving linear systems using the substitution method.

Example: Problem 1 solves the system 8x + 6y = 16 and y = 4, resulting in the solution (-1, 4).

The problems on this page cover various scenarios, including:

Systems where one equation already isolates a variable
Systems requiring manipulation to isolate a variable
Systems with different coefficients and constants

Highlight: The step-by-step solutions provide a clear demonstration of the substitution method, showing how to isolate variables, substitute values, and solve for unknowns.

Each problem follows a consistent format:

Present the system of equations
Isolate one variable (if not already done)
Substitute the isolated variable into the other equation
Solve for the remaining variable
Calculate the value of the substituted variable
Present the final solution as an ordered pair

Vocabulary: Substitution method - A technique for solving systems of linear equations by expressing one variable in terms of another and then substituting this expression into the other equation.

The problems on this page increase in complexity, providing a gradual progression for students to practice and master the substitution technique.
