How do I solve this problem

Answer 1

You would put 6 in for k and 2 in for c, making it "5*6-20+8", which equals 18. Hope this helps! :)

Answer 2

In these problems  u substitute the number specified so in this problem you would put 6 in for k which would makes the problem   5* 6-10c+8  then you put 2 in for c which makes  the problem 5*6-10 *(times) 2+8 so then u do the order of operation so 5 times 6 and u get 30 so now the problem is 30 - 10 *2+8 so now you do  10 times 2 is 20 so the problem is 30-20+8 now you do it from left to right so 30 -20 wich is 10 so the problem is 10 +8  and 10  plus 8 is 18 so i would say that it is 

18
