5(2s-1)+3=3(3s+2)
10s - 5 + 3 = 9s + 6
s = 6 + 5 - 3
s = 8
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(2s-1)+3=3(3s+2)
HELP PLEASE!!

how did you get the 's' by its self?
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?
Yes. I subtracted 9s from both sides.
Ohhh kayy thanks i didn't see at first... Thank You!!
You're welcome. :-)
just to be sure did i do this right?
3(3u+2)+5=2(2u-2)
9u+6+5=4u-4
5u=-15
5/5=-15/5
u=-3
3(3u+2)+5=2(2u-2)
9u+6+5=4u-4
5u=-15
5/5=-15/5
u=-3
Right.
