x + 18 is already simplified to the greatest extent.
Yes, it can be simplified into 4x.
If you mean: -8y-(x-4x)+3y then it is 3x-5y simplified
-2
It can be simplified to: x-5y
what is 5(x-5) plus 6 expanded and simplified
Simplified: 5x + 35 Solved: x = -7
It is already simplified.
4X
No, that's 1/x
4p
x^2-x-6
