Like Terms and Variables
When you have an expression you have to simplify by eliminating all grouping symbols and 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.
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".
If you have a expression that goes; 2x + 5x etc etc Simplifying the like terms is 7x 2x and 5x are like terms, but 2y and 2x are not. The variable needs to be the same.
Lots of expressions are equivalent to it. But for a start, you may want to simplify it, by combining like terms - i.e., add the terms with the variable "w", and separately add the terms without a variable.
They are used to simplify expressions by helping to reduce the numbers that there is
You combine like terms.
Simplify an Expression
12t + 15
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
When you have an expression consisting of several terms added together, and they are not all like terms, and there are like terms separated by unlike terms, you use the commutative law of addition to rearrange the terms so that the like terms are next to each other.
to simplify an expression means to take all the like terms and make them one. for example if the expression is 2x+5x+1x-4 , you would simplify it by adding 2x,5x,&1x because they are all alike... it would become 8x-4
You cannot solve an expression. You can only simplify it. Assuming you mean simplify, you do this by combining like terms. Since both terms have an "r" in them, you simply add the coefficients together. Example: 5x + 2x would be 7x Example: -3y + 8y would be 5y Example: -2p - 4p would be -6p You should be able to simplify your problem now.
If you're asked to simplify an expression, you need to expand all brackets if there are any, and collect all like terms. If the question is a fraction you have to give the answer in its simplest form
Combine like terms. 6x - 2y +7.
Multiply out all brackets (parentheses). Combine "like" terms. "Like" terms are those where any algebraic letters and their powers are exactly the same, but the numbers before them (the coefficients) may be different. Thus 2x2y and 3x2y are like terms and should be combined to make 5x2y. But 2x2y and 3xy2 are not like terms since in the first it is x that is squared while in the second it is y. Similarly, x and x2 are not like terms. Also, when combining terms, remember that x2y is 1x2y.
simplify means to get an expression to its simplest form (a.k.a. combine like terms, add together constants) i.e. x + x + 5 + 3 simplified is 2x + 8
Combine like terms to give 3n + 2
It is: 4k-10+7-7k combines to -3k-3
Only if it contains an equality sign otherwise it is considered to be an expression
(5x -3x) (2y +8y) 2x + 10y
To add and subtract algebraic expressions the simple rule of like terms applies. In your homework that asks for the expression represents the perimeter in units of this trapezoid you will need to find the like terms and simplify.
