How do I solve these inequalitys?

-18 < 2(12-3b)


5p-3(p-6)&#8804;0

Please post the steps to solving them too! Thanks

 

Solve it just like you would solve an equation (but if you multiple/divide by a negative number, you must flip the sign of the inequality)?

-18 < 2(12-3b)
-18 < 24 - 12b
0 < 42 - 12b
12b < 42
b < 3.5

5p - 3(p - 6) &#8804; 0
5p - 3p + 18 &#8804; 0
2p + 18 &#8804; 0
2p &#8804; -18
p &#8804; -9

 

Thanks
but where did 12b come from wouldnt it be 6b

 

Bro, you did it wrong it isnt 12b in the 2nd step.. It's 6b use the distributive property.. Idk how you got 12 2*3b is 6b.. not 12b

 

Chill. A simple typo. The important thing is Jimmy showed him how to do that type of problem.

 

This is correct, so the final answer should be b < 7.

My bad :embar:
