If all the variables are the same, you just add (algebraically add) the numbers. For example:
3a + 4a = 7a
2a - 10a = -8a
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
That equals x.
There is nothing that you can do when you combine like terms that you cannot do without combining them. Some procedures might be easier, though, if like terms are combined.
-6k + 7k = k
The answer depends on how fluently you can work with fractions.
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
6a + 5a = -11 Combining like terms: 11a = -11 Dividing by 11: a = -1
In Math combining like terms is like so if the equation is 4a+4=2a you combined the 4 and the 5 because they are both A
Formula transformation methods include rearranging terms, combining like terms, factoring, expanding, and substitution of variables. These methods are used to simplify or manipulate formulas to make them easier to work with or solve.
Like Terms and Variables
When combining like terms like 2x+3x we add their coeffitients, for example 2x+3x=(2+3)x=5x
Combining like terms.
No. For purposes of combining "like terms", you need terms that have exactly the same variables, with the same exponents (if there are any).
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.
That equals x.
When combining like terms, you could add and multiply. It depends on what the problem is. I am in 6th grade and currently learning algebra. I know that my answer is correct because I already learned this.
