Answer:

If you need a simplified fraction then 
3(x+6)>8-(x-7)
3x+18>8-x+7
2x+18>15
2x>-3
X>-3/2
19+17+4+4=44
56-44=12
20-12=8
No, and she needs 8 more dollars.
If you are solving for x than the answer would be x=4.
Answer:
x=0.875
Step-by-step explanation:
3x-6=2-5x
Add 6 on both sides (6+2)
2x=8-5x
Add 5x on both sides
7x=8
Divide 7 from both sides
x=0.875
