A box contains orange balls and green balls. The number of green balls is seven more than three times the number of orange balls

OverLord2011 [107]

Answer:

52 green, 15 orange

Step-by-step explanation:

g + o = 67 g = green, o = orange, x = total

g = 3o + 7

use substitution: (3o + 7) + o = 67

solve for o:

4o + 7 = 67

4o = 60

o = 60/4 = 15

solve for g:

g + 15 = 67

g = 52
