Determine the solution to the following problem: 2x+5=21 (1 point)

Answer 1

To solve the equation 2x + 5 = 21, we need to isolate x on one side of the equation.

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

Next, divide both sides of the equation by 2 to solve for x:
x = 16/2
x = 8

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