Answer:
7 monkeys and 13 rabbits
Step-by-step explanation:
Let's define x as the number of monkeys that I sold. Then, I sold (x + 6) rabbits.
As I get $6 for each, I need to add the number of monkeys and rabbits I sold and multiply it by 6. That calculation has to be equal to $120 because that's my earnings.
Therefore, the equation we need to resolve is
(x + x + 6)*6 = 120
Let's divide by 6 on each side and add the x's:
(2x + 6)*6/6 = 120/6
2x + 6 = 20
Now we subtract 6 on both sides:
2x + 6 - 6 = 20 - 6
2x = 14
Now we divide by 2:
2x/2 = 14/2
x = 7
Therefore, I sold 7 monkeys and 7 + 6 = 13 rabbits.
