the idea behind this is using the distributive property and combining like terms do you know how to do this?
OpenStudy (anonymous):
yes i just get confused doing it
OpenStudy (photon336):
alright \[3x+5(-4x+12)-(x-3)\]
you see the
5(-4x+12) we need to use the distributive property meaning we multiply 5 by everything in the ( ) what do you think the result for this part of the problem would be?
OpenStudy (photon336):
@Tears1213 we'll do it step by step

ok
OpenStudy (photon336):
so from what I said above, how would you solve the part I indicated?
OpenStudy (anonymous):
yea 40x
OpenStudy (photon336):
3x+ 5(-4x+12) okay.
so see that 5 there and the ( ) ? we can multiply that by everything in the ( )
5*(-4x)+5*12
= -20x+60
Now all you need to do is combine like terms.
3x-20x+60-(x-3)
OpenStudy (anonymous):
ok

do you get how I got that?
OpenStudy (anonymous):
kinda
OpenStudy (photon336):
what don't you understand?
OpenStudy (anonymous):
well i did 3x-20x and got 18x and now im having trouble with the rest
OpenStudy (photon336):
@Tears1213 check your answers you may not have to simplify it anymore
