Zorluk: KolaySimplifying Algebraic Expressions

Simplify the following algebraic expression:

12−3(2y−4)12 - 3(2y - 4)

Which expression represents the fully simplified result?

  1. A
    −6y-6y
  2. B
    18y−3618y - 36
  3. −6y+24-6y + 24Cevap
  4. D
    18y18y

Cevap

The correct simplified expression is −6y+24-6y + 24.
The expression is correctly simplified by first distributing the −3-3 across the terms in the parentheses, which results in −6y+12-6y + 12. Adding the initial 1212 to this new constant gives a final expression of −6y+24-6y + 24.

Adım Adım Çözüm

1
Distribute the −3-3 to both terms inside the parentheses.
12−6y+1212 - 6y + 12
The distributive property requires multiplying the term immediately outside the parentheses by each term inside.
2
Combine the constant terms.
−6y+24-6y + 24
Like terms (the constants 1212 and 1212) must be added together to fully simplify the expression.
