Question

She completes the problem as seen in the steps below.

Answer 1

Answer:

• All her steps are right, and the answer is right as well

Step-by-step explanation:

$2(x + 1) + 1 = 5 \\ 2(x + 1) = 5 - 1 \\ 2(x + 1) = 4 \\ \\ \frac{2(x + 1)}{2} = \frac{4}{2} \\ \\ x + 1 = 2 \\ x = 2 - 1 \\ x = 1$

Answer 2

D. all the steps are incorrect
Step-by-step explanation:
she needs to distribute the 2 into the parenthesis first due to PEMDAS
2x+2+1= 5
2x+3=5 then isolate the x
-3 -3
2x=2
(2x)/2=2/2
x=1
