Answer:

30 dollars left

Step-by-step explanation:

If Lily works for 10 dollars per hour and works 5 hours which adds up to 50 dollars then she buys a sweater for 20 so 50 minus 20 is 30 dollars, so Lily has 30 dollars left over.

6x + y = -39 <br> 3x + 2y = -15 <br><br> elimination using multiplication
vlabodo [156]
Multiply the second equation by 2 so that its 
6x+4y=-30
then subtract 
6x+y=-39
6x+4y=-30
= -3y=-69
divide by -3 to isolate the y
then you get y=23
substitute the y value back into one of the equations to solve for x.
6x+23=-31
solve like you always do and you'll get your x
Congratulations, you solved a problem.
