3x-3+6x=(-5x)+6
1. add like terms (in this case 3x and 6x are alike)
3x+6x=9x
9x-3=(-5x)+6
2. add 5x to each side
14x-3= (-5x+5x cancels out) +6
3. add +3 to each side
14x (-3+3 cancels out)=6+3
14x=9
4. divide each side by 14 to get value of x
14x/14=9/14
(14 cancels out from left side of equal sign) x=9/14
5. answer: x=9/14

3x - 3 + 6x = -5x +6
=>9x + 5x = 9
=>14x = 9
=>x= 9/14

3x+6x+5x=6+3
14x=9
x=9
14
i.e x = 9 upon 14

Place all the x's on one side and whole numbers on the other side. Remember to change "-" to "+" (and vise versa) when crossing the equal sign:
3x + 6x + 5x = 6 + 3
Group like terms:
14x = 9
x = 9/14
