x+y=120_______1

x=4*y_________2

x=4y

substitute 4y for x in equation 1

`4y+y=120

5y=120

eliminate the coefficient of y

y=120/5

y=24

now,input 24 for y in equation 2

`x=4y

x=4*24

x=96

Vesna [10]

Answer:

$20 on each cat and $40 on each dog

Step-by-step explanation:

Call the amount spent on each, cat, x and let the amount spent each dog = y = 2x

So we have the following constraints:

y = 2x (1)

164(x) + 24y <= 4240 (2)

Substituting (1) into 2 for y, we have

164x + 24(2x) <= 4240 simplify

212x <= 4240 divide both sides by 212

x<= $20 on each cat

And y = 2(20) = $40 on each dog

So she can spend $20 on each cat and $40 on each dog
