Answer:
8
Explanation:
first, we need to get rid of either one of the variables on either sides so that we have only one variable on one side to work with. to do this we add -2k to both sides to get rid of the variable on the right.
-5k+-2k+10=-2k+-2k-14.
this leaves you with:
-3k+10=-14.
now, we subtract 10 from each side to isolate the variable.
-3k+10-10=-14-10
from there we have -3k=-24.
in order to get rid of the coefficient attached to the variable, we use the division property of equality. thus, we divide each side by -3.
-3k/-3=-24/-3
and you should get,
k= 8
