Two Step Equations

100

5 + 3x = 11 

x = 2

200

6 - x = 4

x = 2

300

- 5 + 7x = 16

x = 3

400

5 + (x/4) = 10

x = 20

500

3 + (1/2) x = 5

x = 4

Quadratics by factoring

100

x² - 16x + 60 = 0

x = 6, x =10

200

x² + 10x + 25 = 0

x = -5

300

x² - 6x = -8

x = 4, x = 2

400

x² + 15x = -56

x = -7, x = -8

500

x² + x - 12 = 0

x = -4, x = 3
