It is the first answer. Notice that if you multiply it out you get 6x + 30, and they have factored out the 6.

The better deal is 3 for $11
Answer: (7,3)
Step-by-step explanation:
<u>[Please check]:</u> I decoded the equations as follows:
3x-4y=9 and −5x+4y=-23
We can solve this by either of two methods: Algebra and graphing.
<u>Algebra:</u>
Add the two equations:
3x-4y=9
<u> −5x+4y=-23</u>
-2x = -14
x = 7
Use x=7 to solve for y:
3x-4y=9
3(7)-4y=9
21 -4y = 9
-4y = -12
y = 3

The solution is (7,3)
