5x-6 <= 3(2+3x)
5x-6 <= 6+18x --- drop 5x from both sides
-6 <= 6+13x --- subtract 6 from both sides
-12 <= 13x
-12/13 <= 13x/13
.923 <= x
did i do this correctly?

pragathish is right i didnt even notice it the first time
5x-6 <= 3(2+3x)
5x-6 <= 6 + 9x - drop 5x from both sides
-6 <= 6 + 4x
-12 <= 4x
-3 <= x
2007-09-23 23:56:35 · update #1
5x - 6 ≤ 6 + 9x
- 12 ≤ 4x
x ≥ - 3

you committed a mistake in the first line of your solution
5x-6
5x-6
-12
-3
x>/=-3 ANS.

5x-6 <= 3(2+3x)
or 5x-6<=6+9x
or -4x<=12
or -x<=3
or x>=-3

you did it correctly except for the second line, 3*3x is 9x. not 18x

-5x6=3[2+3x]
-30=6+9x
-36=9x

Look at the second line's distributive property.
