The number that is twice as much as five more than a number a? Simplify the answer.

Let us assume the unknown number is n.

Given statement " The number that is twice as much as five more than a number a."

Twice of a is = 2 times of a = 2a.

Now, it is said twice of that number of 5 more than a.

So, we can set an equation as

2a = a + 5.

Subtracting a from both sides, we get

2a - a = a-a + 5

a = 5.

Therefore, unknown number a is 5.
