Answer 1

To solve the equation \( 2x + 5 = 31 \), we'll first isolate \( x \):

1. Subtract 5 from both sides: \[ 2x + 5 - 5 = 31 - 5 \] \[ 2x = 26 \]

2. Divide both sides by 2: \[ x = \frac{26}{2} \] \[ x = 13 \]

Now, we check which number from the set {6, 13, 18, 26} is equal to 13. The only number that matches is:

13
