Let x represent the number of shirts. Let y represent the number of pens.
If shirts are on sale for $11.99 each, then x shirts cost $11.99x.
If pants are on sale for $12.99 each, then y pants cost $12.99y.
The total cost is $(11.99x+12.99y).
Sarah can spend up to $65. Then an inequality that represents this situation is
11.99x+12.99y≤65 (this inequality holds when Sarah can spend $65 too)
or
11.99x+12.99y<65 (this inequality holds when Sarah can spend less than $65).
I think your answer is right
Answer: 
Step-by-step explanation:
Answer:
(-1,-7)
Step-by-step explanation:
Substitute 2x-5 (from the first equation) as the y-value for the second equation, so you have something that looks like this:
2x-5 = -2x-9
Add 2x to both sides: 4x-5 = -9
Add 5 to both sides 4x = -4
Divide both sides by 4: x = -1
Substitute -1 for x in either equation (you'll get the same y-value)
