Best ResponseYou've already chosen the best response.0Are you trying to solve for \(b_2\)?

Best ResponseYou've already chosen the best response.0Ok, 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?

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

Best ResponseYou've already chosen the best response.0Now the easiest thing now is to move that 2 over to the left. Can you do that?

Best ResponseYou've already chosen the best response.0Not quite. 2 is multiplied on the right, so you have to divide, not subtract, to get it back.

Best ResponseYou've already chosen the best response.0Or, to move it over, rather.

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

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

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

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

Best ResponseYou've already chosen the best response.0okay...so \[b _{2}\] =5?
