I understand how to multiply a polynomial by a monomial for example
6pq(3p^2+4q)= 18p^3q+24pq^2
but i don't know how to do problems like this
5(2s1)+3=3(3s+2)
HELP PLEASE!!

Ms. Sue,
5(2s1)+3=3(3s+2)
10s  5 + 3 = 9s + 6
s = 6 + 5  3
s = 8

EmilyMay,
how did you get the 's' by its self?

Algebra:'( 
EmilyMay,
Did you take 9 and subtract it by 10 to get 1s but you just dropped the 1 because a variable always has and invisible 1?

Algebra:'( 
Ms. Sue,
Yes. I subtracted 9s from both sides.

Ms. Sue,
You're welcome. :)

EmilyMay,
just to be sure did i do this right?
3(3u+2)+5=2(2u2)
9u+6+5=4u4
5u=15
5/5=15/5
u=3

Ms. Sue,
Right.
