Best Answer

A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.

True. To solve a three variable system of equations you can use a combination of the elimination and substitution methods.

yes

Isolating a variable in one of the equations.

The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.

2x+7y=29 x=37-8y

The first step is to show the equations which have not been shown.

yes

Isolating a variable in one of the equations.

The first step is to solve one of the equations for one of the variables. This is then substituted into the other equation or equations.

You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.

there is no linear equations that has no solution every problem has a solution

There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.

You use algebra and solve the system(s) of equations using techniques such as elimination or substitution.
