Question

Simplify. 3(x+2y)+5x−y+1
A 8x+y+1
B 8x+5y+1
C 8x+7y+1
D 6xy+5x−y+1

Answer 1

Answer is B.) 8x + 5y + 1

Step by step.

3(x + 2y) + 5x -y + 1

PEMDAS is the rule of math order of operations. It says to perform parenthesis first. Distribute multiply 3 x both variables in ( ).

3x + 6y +5x -y +1

Now combine like terms
This means add x’s then y’s then constants.
You can only add like terms that are the same.

8x + 5y + 1

So B. Is your answer

Answer 2

Answer: 8 x + 5 y + 1

8x+5y+1

so that would be B)
