Question

solve for B, show work
-(3b - 15) = 6 ( 2b + 5 )

Answer 1

first, do the distributive property. what do you get after doing that?

Answer 2

do you know how to distribute?

Answer 3

-3b - ( - 15) = 12b + 35

Answer 4

6 x 5 = 30, not 35 :l and -3b - (-15) can be simplified to -3b + 15.

so our new equation would be -3b + 15 = 12b + 30

Answer 5

do you know what to do from there?

Answer 6

my bad, you can simplify -3b - (-15) o.O how?

Answer 7

yea, when you see two - like that, it means you're adding

Answer 8

:D

Answer 9

so -3b + 15

Answer 10

then
-3b - 12b = 30 + (-15)

Answer 11

hm, that's not the way i would go about it, but yea, that works lol. now just simplify that so you can go to the next step

Answer 12

okay, how would you do it though?

Answer 13

oh, i would add 3b and subtract 30, but you'll get the same answer either way i think

Answer 14

eh, not sure.
-15b = 15
b = -1 ?

Answer 15

yea, that's right

Answer 16

cool, thanks

Answer 17
