Question

Solve. Eight less than 7 times a number is 6. Find the number.

Answer 1

The number is 2

Explanation:

The fastest way to solve this it to retrace the steps. So.....

(7)(x)-8=6

6+8=14

14/7=2

Thus, 2 is your answer.

Answer 2

The word "less than" switches the order around.

So instead of 8 - 7n = 6, our equation is 7n - 8 = 6.

Solving from here, we add 8 to both sides to get 7n = 14.

Now divide both sides by 7 to get n = 2.
