Whats the answer to 4=4 (k+3)

-2=k is the answer. You need to get the expression by its self so you divid by 4 and subtract 3

To solve for k, you first need to distribute the 4 to k+3.

4 = 4 (k+3) = (4*k) + (4*3) = 4k+12

Then you subtract over any constants:

4-12=4k+12-12

And divide out the 4 to isolate the variable:

-8/4 = 4k/4

k=-2
