Twelve times the sum of a number and five is -144. What is the number ?

Twelve times the sum of a number and five is -144 translates to 12(x+5) = -144. Now, we can solve it as

12(x+5) = -144..................Using the Distributive Property

12x+60 = -144

12x = -144 - 60

12x = -204..................Then, divide 12 to obtain

x = -17

-17 is the missing number!

I hope this helped!
