\[16 = half * 4* (3 + b _{2})\]

Are you trying to solve for \(b_2\)?

Ok, so let's start at the top. When you have a multiplication between regular numbers, go ahead and do that first. In this case: \[16 = \frac{1}{2}4(3 + b_2)\] You can do the multiplication of 1/2 * 4. What do you get?

shadowfiend Group TitleBest ResponseYou've already chosen the best response.0
Right. So then we have: \[16 = 2(3 + b_2)\]

Now the easiest thing now is to move that 2 over to the left. Can you do that?

yes....16 2 = 14

Not quite. 2 is multiplied on the right, so you have to divide, not subtract, to get it back.

Or, to move it over, rather.

so 16/2 is 8 right?
 3 years ago

shadowfiend Group TitleBest ResponseYou've already chosen the best response.0
Right. So now we have: \[8 = 3 + b_2\]
 3 years ago

*_Artist_* Group TitleBest ResponseYou've already chosen the best response.0
divide 8 by 3 now?
 3 years ago

shadowfiend Group TitleBest ResponseYou've already chosen the best response.0
No, 3 is added in, so we subtract it this time :)

shadowfiend Group TitleBest ResponseYou've already chosen the best response.0
Remember, we can also rewrite that: \[8 = b_2  3\]

shadowfiend Group TitleBest ResponseYou've already chosen the best response.0
!! Sorry, I meant: \[ 8 = b_2 + 3 \]
 3 years ago

*_Artist_* Group TitleBest ResponseYou've already chosen the best response.0
okay...so \[b _{2}\] =5?
 3 years ago

shadowfiend Group TitleBest ResponseYou've already chosen the best response.0
Right! (Sorry for the delay.)
