Answer:

x = 10

Explanation:

7 x -5 = 65

7 times what? (x) - 5 equals 65

Well we know that x has to be less than 65 and more than 7 and -5.

So 7 must be multiplied by numbers 8, and up.

7 * 8 -5 = 51, NOT 65.

7 * 9 -5 = 58, NOT 65.

7 * 10 -5 = Does equal 65.

Therefore, x is equivalent to 10.
