Question 781652

Solve:

-1 < 5 - 2p < 5

Work I've done:
-1 < 5 - 2p and 5 - 2p <5
subtract 5 from both sides
-6 < -2p and -2p < 0
divide by -2
3 > p and p > 0


You could have done it this way: 


-1 < 5 - 2p < 5


- 1 - 5 < 5 - 2p - 5 < 5 - 5 --------- Subtracting 5


- 6 < - 2p < 0


{{{(- 6)/- 2 < (- 2p)/- 2 < 0/- 2}}} ------- Dividing by - 2


3 > p > 0, which means that: {{{highlight_green(0 < p < 3)}}}


You can do the check!!
