12

Let the unknown number that we have to find be denoted by the symbol X

Now the question tells us that twice the number“so it is 2x.

Next, it says, when twice the number is increased by 5. This means:

2x + 5 = 29

Now we can solve it for X.

Subtract 5 from both sides of the equation:

2x + 5 – 5 = 29 – 5

2x = 24

Now divide both sides of the equation by 2

2x / 2 = 24 / 2

X = 12
