1. we can add them to eliminate y's
3x-4y=-16
<u>-x+4y=24 +</u>
2x+0y=8
2x=8
divide by 2
x=4
sub back
-x+4y=24
-4+4y=24
add 4 both sides
4y=28
divide by 4
y=7
(x,y)
(4,7)
3.
add them to eliminate y's
-5x+3y=12
<u>-2x-3y=-33 +</u>
-7x+0y=-21
-7x=-21
divide both sides by -7
x=3
sub back
-2x-3y=-33
-6-3y=-33
add 6 to both sides
-3y=-27
divide both sides by -3
y=9
(x,y)
(3,9)
1. (4,7)
3. (3,9)

Answer:
IF she bought 8 towels for 39.60 and you are trying to find out how much each one cost you would divide 39.60 by 8 to get your answer but if each towel cost 39.60 then you would times 8 by 39.60.
Step-by-step explanation:
39.60 divided by 8 = 49.5
8 x 39.60=316.8
Answer:
598 possibly because you multiply 46 x 13
