200

What are two different methods you can use to solve a 2 variable equation?

Substitution / Elimination Method

300

Solve using elimination method: 3x- 2y= 4 5x + 3y= -25

(-2, -5)

400

2x +3y –z = 0 x – 2y – 4 = 14 3x + y -8z = 17

(4, -3, -1)

500

3x + y – z = -6 2x – y + 2z = 8 4x + y – 3z = -21

(-1, 4, 7)
