The required number is 12.

Explanation:

To solve the problem first define a variable for the required number.
Let's say, n is our required number.

Then according to the given statement, we have:

4x2=x+34

Add 2 to both sides:

4x2+2=x+34+2

4x=x+36

Subtract x from both sides:

4xx=x+36x

3x=36

Divide both sides by 3:

3x3=363

x=12

That's it!

The number is 12

Explanation:

The phase "is the same as" separates the sentence into two equal parts.
Write an expression for each.

Let ' the number' be x

4 times the number : 4x

Two less than that means: 4x2

The number plus 34 is written as x+34

These two expressions are equal to each other.

4x2 = x+34

4xx=34+2

3x=36

x=12

Check:

4x2 = x+34

4(12)2 = (12)+34

46 = 46
