Answer 1

Given:-

• Three More than twice a number is equal to four less than the number.

To Find :-

• Find the Number

Solution :-

We are given with a Question to find the number with given clues.

• Let x be the Number

According to the question

• Three more than twice a number = 2x+3

• The number minus 4 = x-4

In the question it is given that the both are equal.

• 2x+3= x - 4

• 2x - x = -4(-3)

• x = -7

Also stated that Add 4 consecutive integers and find the sum

Consecutive integers = -8,-9,-10,-11

• Sum = -7+-8+-9+-10+-11 = -45

$\bold{ \red{★Hence \: the \: Number = 7}{} }{} \\ \\ \bold{ \red{★Sum = - 45}{} }{}$
