Find a number such that When 15 is subtracted form 7 times the number the result is 10 more than twice the number?
If we call the number that we're looking for "x", then we can translate the question like this:
When 15 is subtracted from 7x, the result equals 2x + 10
Or:
7x - 15 = 2x + 10
Then it's a simple matter of simplifying the equation. Group like terms on either side of the equal operator:
7x - 2x = 10 + 15
Then add them together:
5x = 25
And factor five out of both sides:
x = 5
Giving you the answer.

If 4 is subtracted from twice a number. The result is 10 less than the number?
Let the number be x: So: 2x-4 = x-10 => 2x-x = 4-10 => x = -6
