help plz

?

yes

yup

yeah still with ya

ok, so we have
r + (2r + 3) = 75
can you solve for r now?

so i divide by two

uh, not quite
we have r + (2r + 3) = 75
let's combine the r's together
r + 2r = ?

what do you mean?

just add them together
r + 2r = ?

dang how?

they are numbers tho

yeah

so its 3rs now?

help?

right...
r + 2r = 3r
so far we have:
3r + 3 = 75
now subtract 3 from each side, what do you get?

these are the answers
A)
24
B)
47
C)
48
D)
51

3r + 3 = 75
now subtract 3 from each side, what do you get?

how do you subtract on two sides?

???????????

ok so 3-3=0 75-3=2 3r+0=72?

yeah!
3r = 72
now divide both sides by 3

ok
one sec

24?

5

5w

hello?

not quite...
r = 24, so we replace "r" with "24"
so w = 2r + 3 = 2(24) + 3 = ?

ok so 27

check your math again
2*(24) = 3 = ?

* means multiply

ok didnt see the times

51

right, so w = 51 and 51 is our answer

thanks!!

can you help with one more?
