Suppose you are selling stuffed animals for 6 each to raise money for you club. you sold six more rabbits than mokeys if you sold 120 worth of stuffed animals, how many of each type did you sell?

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.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
