Solve this and get 30 points !!!!!
jasenka [17]

First of all, don't let "b" confuse you. Know that b = 5/6k = -10, so all you really have to solve for this problem is \frac{5}{6}k = -10.

Before anything else, you have to isolate k. Do this my multiplying both sides by the reciprocal of 5/6.

\frac{6}{5} * \frac{5}{6}k = -10 * \frac{6}{5}

The 6/5 and 5/6 cancel each other out, so we are left with k = -10 * \frac{6}{5}

--> k = \frac{-10 * 60}{5}

---> \frac{-60}{5} = -12

So k = -12.

Hope this helped. Good luck.
