Answer:
5. x= 13
6. x= 9.3 repeating (can't find the symbol for it lol)
7. x= 26
9. x = 11 and y= 3
Explanation:
5. 119 = 9x+2
- subtract 2 from both sides
- divide both sides by 9 for the answer
6. 104= 12x-8
- add 8 to both sides
- divide by 12 on both sides for the answer
7. 5x+78 = 8x-71
- add 71 to both sides
- subtract 5x from both sides
- divide both sides by 3 for answer
