You have no information in this type of problem that will allow you to solve for "X". Combine the like terms, (2x + x) + (5-4), and that's as far as you can break this down. Variables (those of the highest power, if applicable) are typically placed first in the result, so even though 1+3x is correct, 3x+1 is the better answer.

5+2x-4+x=What? is not an equation. For this statement to be an equation you must have some quantitive value that it is equal to (What?) is not a quantitive value.

However you can say that 5+2x-4+x is the same as (combine like terms) 5 and -4/2x+x

+ 1 / 3x and you have 1+3x which is equivelent or the same as 5+2x-4+x.

5+2x-4+x
=5-4+2x+x (Commutative Property of Addition)
=1+(2-1)x (adding like terms)
=1+1x (Distributive Property/adding like terms)
=1+x (Identitive Property of Multiplication)
=x+1 (Commutative Property of Addition)

The last step isn't always necessary, but it's a good idea to get into the habit of putting the most complicated parts of an expression or equation or inequality first, i.e.: x^3+x^2+x+1

They're asking you to simplify this expression.

First group likes with likes with the associative property.
(5-4)+(2x+x)

Then do the math. (1)+(3x) or 3x+1

5-4= 1
2x + x = 3x
3x + 1
