Answer:

x+ (2x+3) +(x+2)=45

Step-by-step explanation:

First number is x

So using this ,second number which is three more than twice of the first can be written as 2x+3

Now , The third number is two more than the first so it is x+2

Sum of the three numbers can be written as

x+ (2x+3) +(x+2)

In the question it is given that the sum is 45 so we can equate the equation in x to the given sum to solve it for x .

Hence

x+ (2x+3) +(x+2) =45
