To determine the solution to the equation 2x + 5 = 21, we need to isolate the variable x. Here are the steps to solve the equation:
1. Start with the equation: 2x + 5 = 21.
2. Subtract 5 from both sides of the equation to get rid of the constant term: 2x + 5 - 5 = 21 - 5.
This simplifies to: 2x = 16.
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 given equation is x = 8.
Determine the solution to the following problem: 2x+5=21 (1 point) Responses 26 26 13 13 8 8 16
