Answer:
The equation to be used is [tex]\frac{3}{4}(x+8) =-12[/tex]
Step-by-step explanation:
Let us call Gopal's number [tex]x[/tex], then he is says [tex]x+8[/tex] multiplied by [tex]\frac{3}{4}[/tex] is -12; to put it another way,
[tex]\frac{3}{4}(x+8) =-12[/tex].
This is the equation we get, and solving it will give us the value of [tex]x,[/tex] the Gospal's number.
