Question

If a number is added to the numerator of 2/3 and twice as much is subtracted from the denominator, the result is -1. Find the number.

Answer 1

The number = 5

Explanation:

Let the number be x

`(2+x)/(3-2x)=-1\\\\2+x=-1*(3-2x)\\\\2+x=(-1)*3-(-1)*2x\\\\2+x=-3+2x\\\\x=-3+2x-2\\\\x-2x=-5\\\\-x=-5\\\\x=5`
