Solution of Equation

There are 50 donkeys and chickens on a far.  There are a total of 174 legs.  Which system below can be used to figure out how many of each animal the farm has?

• d + c = 174
  4d + 2c = 50

• d + c = 50
  4d + 2c = 174

• d + c = 50
  2d + 4c = 174

• d + c = 174
  2d + 4c = 50

Solve the equation 2x - 3 = x + 5 graphically.

• (8,13)

• x = 8

• x = 13

• x = 2

• (-2, 3) and (3, 3)

• x = 3

• x = -2, 3

• x = 2, 3

• x = 1.646, -3.646

• (1.646, 2.292) and (-3.646, -8.292)

• x = 2.29, -8.29

• x = 1.65, -3.65
