Question

Determine the solution to the following problem:

2x+5=21

Answer 1

To find the solution to the equation 2x + 5 = 21, we need to isolate the variable x.

First, we subtract 5 from both sides of the equation:
2x + 5 - 5 = 21 - 5
This simplifies to:
2x = 16

Next, we divide both sides of the equation by 2 to solve for x:
(2x) / 2 = 16 / 2
This simplifies to:
x = 8

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