Solving Systems of Equations

Front

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

Back

The system has coinciding lines, meaning the equations represent the same line on a graph.

What is the graphical representation of parallel lines in a system of equations?

Back

Parallel lines indicate that there is no solution to the system, as the lines never intersect.

What are the steps to solve a system of equations using substitution?

Back

1. Solve one equation for one variable. 2. Substitute that expression into the other equation. 3. Solve for the remaining variable.

What are the steps to solve a system of equations using elimination?

Back

1. Align the equations. 2. Multiply if necessary to match coefficients. 3. Add or subtract the equations to eliminate one variable. 4. Solve for the remaining variable.
