X is 45, z is 45, and y is 90
Answer:
50(115-y) + 25y = 4125 [from eq2]
5750 - 50y + 25y = 4125 [distribute]
5750 - 25y = 4125
-25y = -1625
y = 65 [divide both sides by (-25)]
There are 65 small boxes.
Put that value into either equation (now, which is easier?) to solve for x:
x = 115 - y
x = 115 - 65
x = 50
There are 50 large boxes.

Answer: 4
<u>Step-by-step explanation:</u>
Melinda: y = 10x + 22
George: y = 13x + 10
13x + 10 = 10x + 22
<u>-10x </u> <u>-10x </u>
3x + 10 = 22
<u> -10 </u> <u> -10 </u>
3x = 12
<u>÷3 </u> <u> ÷3 </u>
x = 4
Answer:
n=3
Step-by-step explanation:
(five times a certain number) 5*3=15
(three less) 15-3=12
