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
Well, let's take a moment to appreciate these lovely variables, f and g. To simplify this expression, we can combine like terms. So, when we combine the terms with f, we get 5f - 7f + 3f, which simplifies to f. And when we combine the terms with g, we get -3g - 4g, which simplifies to -7g. So, the simplified expression is f - 7g. Remember, there are no mistakes in math, just happy little accidents.
To simplify the expression 18 + 7x - 12 + 5x, you first combine like terms. Combine the constants (18 and -12) to get 6. Then, combine the x terms (7x and 5x) to get 12x. Therefore, the simplified expression is 6 + 12x.
