Question

-4p-10(2p-3)=22-7(1-2p)

Answer 1

Shenita, I can help with this.....
ok, first distribute the minus signs in front of the 10 and 7 when you simplify the equation....you'll get -4p-20p+30=22-7+14p See so far?

Answer 2

yes

Answer 3

Then continue simplifying like terms on each side....remember that -4p-20p=-24p
and you'll get -24p+30=15+14p With me so far?

Answer 4

yes

Answer 5

Now start to do your inverse operations...I usually teach my students to do the variables first, but it doesn't really matter....and I start with the SMALLER of the variables....that will help avoid some negatives ....So I would ADD 24p to both sides (I add them underneath each side....to get 30= 15 +38p...see this? Write it with adding the 24p underneath each variable term

Answer 6

See how -24p is smaller than 14p??

Answer 7

yes negative

Answer 8

Now do the inverse of a positive 15 to both sides which is to subtract 15 (underneath again)...and you'll get 15=38p

Answer 9

just checking my math...are you getting otjer answers with fractions?

Answer 10

what do u mean

Answer 11

when you divide both sides by 38 (the last step) you'll get 15/38=p

Answer 12

ok

Answer 13

which doesn't reduce....is this part of a homework assignment? Some books like to have fractional answers....some stay away from them...

Answer 14

yes she wants it to stay as fractions

Answer 15

yeah!! love that teacher!! PLEASE work with fractions as often as possible.....instead of making everything more difficult turning them into decimals!!!

Answer 16
