Determine the solution to the following problem: 2x + 5 = 21
To solve the equation 2x + 5 = 21, we can follow these steps:
1. Start by subtracting 5 from both sides to isolate the term with x:
2x + 5 - 5 = 21 - 5
This simplifies to: 2x = 16
2. 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 equation 2x + 5 = 21 is x = 8.
To find the solution to the equation 2x + 5 = 21, follow these steps:
Step 1: Start with the given equation: 2x + 5 = 21.
Step 2: Subtract 5 from both sides of the equation to isolate the variable: 2x + 5 - 5 = 21 - 5.
Simplifying this equation gives us: 2x = 16.
Step 3: 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 equation 2x + 5 = 21 is x = 8.
To solve the equation 2x + 5 = 21, we need to isolate the variable x by performing inverse operations.
