Question

Jaelyn solved the equation below and got an answer of p= 3. Is her answer correct? Show how you know or explain your thinking.

3(p+2)+9=8+6p

Answer 1

No, Jaelyn is incorrect because 18 is not equivalent to 24.

Explanation:

3(p+2)+9=8+6p

Step 1 : substitute p
3(3+2)+9=8+6x3

Step 2 : distribute 3 into 3 and 2
9+6+9=8+6x3

Step 3 : multiply 6 by 3
9 + 6 + 9 = 18

Step 4: add
24 = 18
