First, we solve the exercise for x coefficients:
Now, we solve the rest of the exercise:
Now we obtain:
\( 74+32+6+4+4=\text{?} \)
Like terms are terms that have exactly the same variable part. For example, 3x and -2x are like terms because they both have 'x'. The numbers 3 and -1 are also like terms because they're both constants (no variables).
Because 3x means 3 times some unknown number, while 3 is just the number 3 by itself. They represent completely different mathematical objects! Think of it like trying to add apples and oranges - they stay separate.
Yes! Always start by identifying and combining like terms before doing anything else. This makes your expression as simple as possible and prevents mistakes in later steps.
Your final answer should have no more like terms to combine. In this case, is fully simplified because x and 2 are different types of terms that can't be combined further.
For simplifying expressions (not solving equations), focus on combining like terms first. Since we're only adding and subtracting here, you can group terms in any order: (3x - 2x) + (3 - 1) = x + 2.
