Which expression equals 6x − 5y + 2 − 8x + 3( y + 5)?
A) 3x − 2y + 17
B) −3x + 2y + 17 ***
C) −2x − 2y + 17
D) −2x − 2y − 17
Oops it's b
I pock c
I pick c
Is right
To simplify the expression 6x − 5y + 2 − 8x + 3( y + 5), we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):
1. Start with the expression inside the parentheses: y + 5
This expression is already simplified and cannot be simplified further. So it remains y + 5.
2. Multiply 3 with the expression y + 5: 3 * (y + 5)
Distribute the 3 to both terms in the parentheses: 3y + 15
Now we can rewrite the expression as: 6x − 5y + 2 − 8x + 3y + 15
3. Combine like terms:
Combine the terms with x: 6x − 8x = -2x
Combine the terms with y: -5y + 3y = -2y
Our simplified expression is now: -2x - 2y + 17
Therefore, the correct answer is option B) -3x + 2y + 17.
