Number 9 please I need help hurry

Mathematics
1 answer:
liberstina [14]3 years ago
8 0

Answer:

x=8

Step-by-step explanation:

Make all the denominators the same

3(x-4/10)=6(3/5)-2(x-5/15)

(3x-12)/30=18/30-(2x-10)/30

Cancel out all the denominators because they're the same

3x-12=18-2x+10

3x-12=28-2x

Add 12 to both sides

3x=40-2x

Add 2x to both sides

5x=40

Divide both sides by 5

x=8
