Let's call the number " n " .

Subtracting three from two times a number is three more than four times that number.

Subtracting 3 from 2 times n = 3 more than 4 times n .

Subtracting 3 from 2n = 3 more than 4n .

2n - 3 = 3 more than 4n

2n - 3 = 3 + 4n Now we can subtract 4n from both sides of this equation.

2n - 3 - 4n = 3 And add 3 to both sides of the equation.

2n - 4n = 3 + 3 Combine like terms.

-2n = 6 Divide both sides by -2 .

n = -3
