12 less than the quotient of a number and seven is -2 find the number

A quotient is the result of a division.
Let the unknown number be x.

We translate the problem into an equation, piece by piece.

"quotient of a number and seven"  ---->   x/7

"12 less than the quotient of a number and seven"  ---->    x/7 - 12

The word "is" means "="
x/7 - 12 =

All the above is -2, so it equals -2.

x/7 - 12 = -2



First, add 12 to both sides and simplify.






Next, multiply both sides by 7.





The number is 70.
