well dear Gurly Gurl
1.3x+6.7 ≥ 3.1x-1.4
1.3x - 3.1x ≥ -1.4 - 6.7
- 1.8 x ≥ -8.1
{ multiply this inequalities by ' -1 ' }
+1.8x ≤ + 8.1
x ≤ (8.1) / (1.8)
x ≤ 4.5
( - infinity , +4.5 ]

Gurly -- try actually paying attention in school and reading your books and studying and trying work yourself instead of wasting 5 points a pop on getting point whores to help you cheat on your school work. This is like your 10th question in under an hour that asks people to help you cheat. YOU figure it out and post what YOU think the answer is, THEN people can actually help you LEARN something.
