Answer:

x = -13

Explanation:

Let the number be x. ATQ,

(3)/(4)(x-7)=-15

The above equation shows Three-fourths of the difference of a number and 7 is negative fifteen. We need to find the number.

cross multiplying both sides,

$3(x-7)=-60\\\\x-7=-20\\\\x=-20+7\\\\x=-13$

So, the number is -13.
