Option A:
All of Jaiden's work is correct. The solution is x = 31.
Solution:
Given equation is 3x – 8 = 2x + 23.
Step 1: 3x – 8 = 2x + 23
Subtract 2x on both side of the equation, we get
⇒ 3x – 8 – 2x = 2x + 23 – 2x
⇒ x – 8 = 23
Step 2: x – 8 = 23
Add 8 on both sides of the equation.
x – 8 + 8 = 23 + 8
x = 31
Step 3: x = 31
The solution is x = 31.
Option A is the correct answer.
So, all of Jaiden's work is correct. The solution is x = 31.
