Question

What number would make 2x + 5 = 31 true

Answer 1

To solve the equation \(2x + 5 = 31\), we need to isolate \(x\).

Here's how to do it step by step:

1. Subtract 5 from both sides of the equation:
\[
2x + 5 - 5 = 31 - 5
\]
Simplifying this gives:
\[
2x = 26
\]

2. Now, divide both sides by 2:
\[
\frac{2x}{2} = \frac{26}{2}
\]
Simplifying this gives:
\[
x = 13
\]

So, the number that makes the equation \(2x + 5 = 31\) true is \(x = 13\).
