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
