~~x+2y=12  \\  ~~3x-10y=0 \\&#10;~------ \\~ -3/x+2y=12 \\  ~~~~~~3x-10y=0 \\ ------- \\ -3x-6y=-36 \\ ~~~~3x-10y=0 \\ +------- \\ ~~~~-16y=-36 \\ \\  ~~~~y= \frac{36}{16}\rightarrow \boxed{\frac{9}{4}} \\  \\
x+2. \frac{9}{4}  =12 \\  \\ x+ \frac{18}{4} =12 \\  \\  \frac{4x+18}{4} =12 \\  \\ 4x+18=48 \\ 4x=30 \\  \\ x=\boxed{\frac{15}{2}}

Lee worked a total of 30 hours at two jobs last week her combined pay from the jobs was $240 she earned $9 per hour working at t
Sonja [21]

Answer:she spent 10 hours working in her aunt's store last week.

Step-by-step explanation:

Let x represent the number of hours that Lee spent working at the movie theater.

Let y represent the number of hours that Lee spent working at her aunt's store.

Lee worked a total of 30 hours at the movie theater and her aunt's store. This means that

x + y = 30

Her combined pay from the jobs was $240. She earned $9 per hour working at the movie theater and $6 per hour working in her aunt's store. This means that

9x + 6y = 240 - - - - - - - - - -1

Substituting x = 30 - y into equation 1, it becomes

9(30 - y) + 6y = 240

270 - 9y + 6y = 240

- 9y + 6y = 240 - 270

- 3y = - 30

y = - 30/ - 3 = 10 hours
