Question

The product of a number and -7 amounts to seven times the sum of that number and 20. Find the number.

Answer 1

Answer: -10

Explanation:

If you put it in an equation it would be -7x=7(x+20). You would then -7x to both sides to get -14x=140. Just divide -14 on both sides to isolate x. This equates to -10. If you put -10 back into the equation then it says that 70 is 7 times larger than 10. Which it is.
