Answer:
x = -13
Step-by-step explanation:
Let the number be x. ATQ,
[tex]\dfrac{3}{4}(x-7)=-15[/tex]
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,
[tex]3(x-7)=-60\\\\x-7=-20\\\\x=-20+7\\\\x=-13[/tex]
So, the number is -13.
