Answer: x=5 y=-6
(5,-6)
Step-by-step explanation:
Solve by elimination
multiply x-5y=35 by 3
= 3x-15y=105
-
divide 9 on both sides
y= -6
Now solve for x
you must plug in -6 for y in either equations
i plugged in -6 for y in 3x-15y=105
subtract 90 on both sides

Step-by-step explanation:
<u>System of equations</u>
Kathy sells candles for $3 and flowers for $5. Let's set the following variables:
x = number of candles Kathy sells
y = number of flowers Kathy sells
She plans to sell 200 items, thus:
x + y = 200
She also likes to earn $2,500. The equation for this condition is:
3x + 5y = 2500
The system of equations is
