Question

Six less than seven times a number is equal to -20

Answer 1

Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2

You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
The answer has been approved.

Hope this Helps! :)
