You can add and subtract any like terms. Since 8w, -4w, and 4w are all like terms, since 8, -4, and 4 all tell how many w's you have. This is the essentially same as saying "There are 8 apples, subtract 4 apples, and add 4 apples." (Don't forget that 8w-4w is the same as 8w + -4w). To solve, just add 8, subtract 4, and add 4. Leave w alone. The answer is 4w.

How do you solve 2x-3x plus 1?
2x-3x+1 can be simplified (by combining like terms, or terms with the same number/type of variables) to -x+1. This is not an equation, but an "expression," meaning that there is no equals sign, and you cannot solve for x without an equals sign. If, for instance, that entire expression was equal to 7, -x+1=7 -x = 6 x = -6
-4x plus 5x combining like terms?
That equals x.
What does it mean to simplify an algebraic expression?
It means to rewrite the expression so that it is in its simplest form. You can do this by combining like terms. For example: The equation 2x + 3x = 5 can be simplified to 5x = 5 by combining the "x's".

What is the difference between an expression and an equation?
An expression does not include an equals sign (=) For eg: 2x+3 would not be an equation but an expression However, 2x+3=0, is definitely an equation with a solution x= -3/2. An expression does not have a definite solution. An expression is a set of terms with mathematical operations combining them. An equation consists of two expressions with an equals sign between them. An expression is a collection of terms and does not have an = sign An equation is a collection of terms but has an = sign between them.

How do you simplify by combining like terms?
You add (or subtract) like terms. This will reduce the number of terms in the expression and that is the extent of simplification that you can achieve using this process.
What is this equal 5x 2y 19 x - 2y -1?
The given expression is 5x + 2y + 19x - 2y - 1. To simplify this expression, we combine like terms. Combining the x terms gives us 24x (5x + 19x) and combining the y terms gives us 0y (2y - 2y). Therefore, the simplified expression is 24x - 1.
