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.

To add like terms, find the terms that have the same (or no) variable, and combine the coefficients of the terms. For instance, if you have a+b where a and b are real numbers, you can combine them.

You can combine like terms - combine the terms that have a "t" in them; separately, combine the terms that don't.

no, combining like terms means combine the terms that are the same 15+x+6+x=28 combine like terms 21+2x=28 2x=7 x=3.5

You need to do what's called combining like terms. _________________________________________________________________ If you have (7x+74y-9z+68) + (9q-2x+19z-60), you group them together, STEP 1: (7x+74y-9z+68) + (9q-2x+3x+19z-60) ===> (7x+3x-2x)+(74y)+(-9z+19z)+(9q)+(68-60) _________________________________________________________________ Now, we need to evaluate. All we do is mentally remove the variables, but not really. Work as if they were constants, but only for addition and subtraction. STEP 2: (8x)+(74y)+(10z)+(9q)+(8) _________________________________________________________________ Finally, remove the parentheses, and for the sake of tidiness organise the variable alphabetically like shown below, and there is your answer: ANSWER: 9q+8x+74y+10z+8

Unlike terms are terms in an equation that are different. These terms cannot be combined. Like terms, however, can be combined.

All multiples of x are like terms, as all multiples of x2 are also like terms. To combine terms is simply to add them up. So if you have an equation such as, 3x2 + 4x2 + 2x + 6x + 10 = 0, you can combine the like terms; the result is 7x2 + 8x +10 = 0.
