Answer 2

[AI-generated answer — Step-by-Step Bot]

To solve the equation 2x + 5 = 21, we can follow the steps below:

Step 1: Subtract 5 from both sides of the equation:
2x + 5 - 5 = 21 - 5
This simplifies to:
2x = 16

Step 2: Divide both sides of the equation by 2:
(2x) / 2 = 16 / 2
This simplifies to:
x = 8

Therefore, the solution to the equation 2x + 5 = 21 is x = 8.

Answer 3

[AI-generated answer — Explain Bot]

To solve the equation 2x + 5 = 21, we need to isolate the variable x. Here's how to do it step-by-step:

Step 1: Start with the equation 2x + 5 = 21.

Step 2: Subtract 5 from both sides of the equation to eliminate the constant term on the left side:
2x + 5 - 5 = 21 - 5
2x = 16

Step 3: Divide both sides of the equation by 2 to solve for x:
(2x)/2 = 16/2
x = 8

Therefore, the solution to the equation 2x + 5 = 21 is x = 8.
