1. 2x + 7 + 3x + 5 =5x+12
2. 3x + 9 + 4x + 3 =7x+12
3. 5x - x = 4x
4. 5y + 7y = 12y
5. 7 + 6y + 5 =6y+12
6.2 + 6x + 4 + x = 6+7x
7.4 + 5y + 6 + 2y = 10+7y
8. 3x + 9 + 4x - 5 =4+7x
9.8+y-5+ 2y = 13+1y
10. 6y + 4 + 8y + 9 =14y+13
11. 2+x-1 + 4x=1+5x
12. 8y + 4y = 12+

pls i need the answers like now!!
