Simple,its just like this:
6x+1+7-3
=6x+8-3
=6x+5
3x + 8
It is a linear expression in one variable, x. It is not an equation and so cannot be solved. It can be simplified to -6x-27.
2(3x + 25) 6x + 50
6x-2y
We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z. (If we have 2 of something and add three of the same thing and then 5 of the same thing we will end up with 10 of that thing).Likewise we can combine the x's.6x - 2x = 4x. (You could think of this as 6x + - 2x if this helps with the idea of "combining".)Therefore we are able to simplify this expression as:2z + 3z + 5z + 4 + 6x - 2x = 10z + 4 + 4x.
3x + 8
10x - 17
It is a quadratic expression in the variable x.
Combine like terms. 6x - 2y +7.
That will depend on the plus or minus value of 4y in order to simplify the given expression
It is a linear expression in one variable, x. It is not an equation and so cannot be solved. It can be simplified to -6x-27.
2(6x + 10) is an algebraic expression in one unknown variable. It is not capable of doing anything.
6x + 9 + 2x = 8x + 9
2(3x + 25) 6x + 50
7x + 7 + 6x - 9 = 13x - 2
6x-2y
We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z.
