-16x + 2 + 18x
'Like' terms are those which contain the same factor; in this case 'x' So taking -16x + 18x =. 18x - 16x = 2x
So it becomes 2x + 2
NB The '2' , on its own is a constant, so is not a 'like' term.
Similarly, something like 2x^3 + 3x^2 + x^3 - x^2 .
The 'x^3' are like terms , and the 'x^2' are like terms, but 'x^3' is unlike to 'x^2'.
So collecting like terms it would become 4x^3 + 2x^2 .
When you do something like 2x^2(2x + 1) , this is NOT collecting like terms , but FACTORING.
Hope that helps!!!!!
Add them together and so -16x+2+18x becomes 2x+2
Combine like terms. 6x - 2y +7.
There are 3 terms in the algebraic expression of: 3y+9+7x
15b + 13c - 12b + 10c + 8 = 3b + 23c + 8
2
Two of them
You combine like terms.
12t + 15
Combine like terms to give 3n + 2
Combine like terms. 6x - 2y +7.
You can combine like terms - combine the terms that have a "t" in them; separately, combine the terms that don't.
There are no like terms here.
12x+14
3x + x = 4x
There are no like terms in the expression 3x + 7
1 - 5x + 7x is an expression, not an equation (no equals sign), so you cannot solve for x. You can, however simplify (combine like terms) and get 1 + 2x.
Like terms are: 5x -7x +2x and 3 -5
Combine like terms, meaning add 12X plus 4X which is 16X and then you add 25Y plus 15Y which equals 40Y so the answer will be 16x+40y. combine like terms means add the ones with the same variable.
