Question

Seven times a number k plus 12 equals
sixty eight. What is the number?

Answer 1

Seven times a number k plus 12 equals sixty eight

According to the problem

`7k + 12 = 68 \\ 7k = 68 - 12 \\ 7k = 56 \\ k = (56)/(7) \\ \boxed{k = 8}`

The number is 8.

Answer 2

k=8

Explanation:

subtract 12 from both sides giving you 56 then divide that by 7 giving you 8
