Applying substitution to solve a system of equations with infinite many solutions

The video tutorial explains how to solve systems of equations using the elimination method. It begins by identifying which variable to isolate and solve, focusing on variables with a coefficient of 1. The tutorial demonstrates solving for Y and substituting its value into another equation. The process leads to a consistent solution with infinite solutions, as the equations represent lines that overlap on a graph.

What is the first step in solving systems of equations using elimination?

• Identify the variable to isolate

• Graph the equations

• Multiply the equations

• Add the equations

When no variable is isolated, what should you look for in the equations?

• A variable with a coefficient of 2

• A variable with a coefficient of 0

• A variable with a coefficient of 1

• A variable with a negative coefficient

What operation is used to isolate the variable Y in the equation?

• Subtraction

• Division

• Addition

• Multiplication

What is the result when the equations are solved and simplified?

• Two solutions

• Infinite solutions

• One solution

• No solution

What does it mean when the solution is consistent and dependent?

• The equations are parallel

• The equations intersect at one point

• The equations have no intersection

• The equations overlap completely
