To solve the equation 2x + 5 = 21, follow these steps:
1. Start by subtracting 5 from both sides of the equation to isolate the variable.
2x + 5 - 5 = 21 - 5
This simplifies to:
2x = 16
2. Next, divide both sides of the equation by 2 to solve for x.
(2x) / 2 = 16 / 2
This simplifies to:
x = 8
The solution to the equation 2x + 5 = 21 is x = 8.
Determine the solution to the following problem:
2x+5=21
