Respuesta :

remember, you can do ANYTHING to an equaiton as long as you do it to BOTH SIDES

we can try to get k by itself bymaking that -17 into 0 since k+0=k

-17+17=0 right so

K-17=-12
add 17 to BOTH SIDES
K+17-17=17-12
K+0=5
K=5
We'll just isolate the variable to find what the variable stands for.

K - 17 = - 12
  +17      +17

k = 5

Plug it back in.

k - 17 = - 12

5 - 17 = -12
-12 = -12

So yes, it is correct.
