FLASHCARD SYSTEM OF EQUATIONS

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the set of values that satisfy all equations simultaneously.

Front

What does it mean to solve a system of equations using elimination?

Back

Solving a system of equations using elimination involves adding or subtracting the equations to eliminate one variable, making it easier to solve for the remaining variable.

Front

How do you represent a word problem as a system of equations?

Back

Identify the variables, translate the relationships and conditions into equations, and ensure the equations reflect the problem's constraints.

Front

What is the graphical interpretation of a system of equations?

Back

The graphical interpretation involves plotting each equation on a coordinate plane. The point(s) where the lines intersect represent the solution(s) to the system.

Front

What is the substitution method in solving systems of equations?

Back

The substitution method involves solving one equation for one variable and substituting that expression into the other equation.

Front

What is the significance of the coefficients in a system of equations?

Back

Coefficients represent the relationship between the variables in the equations. They determine the slope and position of the lines when graphed.

Front

What does it mean if a system of equations has no solution?

Back

A system has no solution if the equations represent parallel lines that never intersect, indicating that there are no values that satisfy both equations.

Front

What does it mean if a system of equations has infinitely many solutions?

Back

A system has infinitely many solutions if the equations represent the same line, meaning every point on the line is a solution.

Front

How can you check the solution of a system of equations?

Back

You can check the solution by substituting the values back into the original equations to see if they hold true.

Front

What is the role of constants in a system of equations?

Back

Constants in a system of equations represent fixed values that affect the position of the lines on a graph.
