Question

If 9 is subtracted from 4 times a number, the result is 91.

Find the number.​

Answer 1

Answer:6(x)-9=57

Add 9 to both the side.

6(x)-9+9=57+9

6(x)=66

Divide both the side with 6.

6(x)/6=66/6

x=11

So the value of the unknown number is 11.

[Lets check the value of x

6(11)-9

=66–9

=57]

So according to me, the value of x is 11.
