Question

Three more than twice a number is equal to four less than the number. Find the number. ​

Answer 1

In context to question asked,

We have to determine the value of the number,

As per question,

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

So, let the number be x

So, twice of the number will be $=2 \times x = 2x$

So, three more than twice of the number will be $=(2x+3)$

While,

Four less than the number will be $=(x-4)$

So, from above,

We can say that,

$2x+3 = x-4$

So, for solving the expression, we will separate the like terms on one side,

So, we will shift x from RHS to LHS,

We will get,

$2x -x = -4-3\\=>x = -7$

Hence, value of the number will be -7.

Answer 2

Answer:

The value of number is -7 .

Step-by-step explanation:

Given -

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

To find -

The number

Solution -

Let, The number is x

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

Four less than the number = $x-4$

From the given information ,

$3+2x= x-4$

Shift same variable number number to LHS

$2x-x=-4-3$

$x=-7$

∴ The value of number is -7 .
