I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a

Which could be used to solve this equation? 3 and one-fifth + n = 9 Subtract 3 and one-fifth from both sides of the equation. 3

dybincka [34]

Answer:

Subtract $3\frac{1}{5}$ from both sides.

Step-by-step explanation:

We want to isolate the variable $n$ . To do this, we have to get rid of $3\frac{1}{5}$ , which we can do by subtracting itself, since it equals 0.

$3\frac{1}{5} + n =9$

$n = 5\frac{4}{5}$
