System of Equations

Which system of equation method would be the best one to use given?

• Continuous

• Elimination

• Substitution

• Graphing

Given the system of equation 2x + y = 6 -2x + 2y = 12 what would be the FIRST step?

• Eliminate the y values

• Eliminate the x values

• Substitute 2x + y for x in the second equation

• Multiply both equations by -2

If using the substitution method, given the system

6x - 4y = -5

2x + y = 3

what would be the FIRST step?

• Solve the second equation for y

• Substitute 2x + y for y in the first equation

• Eliminate the x values

• Find the intersection of the two equations

Which system of equation method would be the best one to use given? y = 3x + 8 4x + 2y = 6
