An independent system of equations is...

• consistent

• has exactly one solution

• no solution

• both 1 and 2

A system of equations that is dependent has...

• a consistent system

• infinite solutions

• two or more linear equations

• all of the above

Substitution method for solving systems of equations includes...

• two or more linear equations

• solving for one variable, then substituting the number into the other equation

• answers 1 and 2

• solving for only x, then using the number as the only solution for x and y

The elimination method for solving systems of equations includes...

• no solutions

• adding or subtracting equations to eliminate a variable in the system

• it's eliminated so you don't have to solve for that variable

• only infinite solutions

The solutions for systems of equations includes...

• infinite solutions

• graphing and substitution

• substitution and elimination

• graphing, substitution and elimination

Substitution method for solving a system of equations includes...

• When the coefficients of one variable are the same or opposites, or when it is not convenient to use graphing or substitution.

• When you want a visual display of the equations, or when you want to estimate a solution.

• When one equation is already solved for one of the variables, or when it is easy to solve for one of the variables.

• The substitution method involves none of these.
