Divide by -15 on each side and change the inequality sign
OpenStudy (unklerhaukus):
[you have to change the direction of the inequality sign when ever you mulitply or divide by a negative]
OpenStudy (anonymous):
okay can you break it down for me
OpenStudy (unklerhaukus):
-15x< 130
step 1 divide both sides by 15
-15x/15< 130/15
<
now divide by -1

no i mean i did not know how to find the answer
OpenStudy (anonymous):
-x < 26 / 3
x > -26 / 3
The inequality changes sign whenever you multiply or divide by a negative number, which in this case it is multiplied by -1 or divided by -1.
