How to solve k (a) = 4a + 2: find k (a-3)

If you meant to say k = (-3)

First thing you would do is plug in the (-3) to a

Your equations would look like this:

k (a) = 4 (-3) + 2

You would multiply 4 * - 3, giving you - 12.

k (a) = 12 + 2

Then you would add 12 + 2, giving you 14.

k (a) = 14

k (a) would equal 14.

K (a) = 4 (-3) + 2

K (a) = -12+2

K (a) = -9
