Question: 1 / 400

Solve for x: If 2x + 5 = 13, what is x?

x = 3

x = 4

To solve the equation 2x + 5 = 13, the goal is to isolate the variable x.

First, subtract 5 from both sides of the equation to eliminate the constant term on the left side. This gives:

2x + 5 - 5 = 13 - 5, simplifying to:

2x = 8.

Next, to solve for x, divide both sides of the equation by 2, resulting in:

x = 8 / 2, which simplifies to:

x = 4.

Therefore, x equals 4, making this result the correct answer. This value can be verified by substituting it back into the original equation. When x = 4 is substituted into 2x + 5, the equation becomes 2(4) + 5, which equals 8 + 5, resulting in 13, confirming that the solution is indeed correct.
