How do you determine if given values are a solution to a system of linear equations?

How do you find the solution to a system of linear equations on a graph?

Using substitution what is the easiest way to start this problem?

• Solve for x in equation 2

• Solve for x in equation 1

• Solve for y in equation 2

• Solve for y in equation 1

When using elimination, what is the first thing you should do?

• Cancel out the y's immediately by adding the equations

• Check all coefficients first to make the best decision

• Multiply equation 1 by -1
