Answer:

Explanation:

Also written as-

4x - 27 = x

+ 27 +27

(add 27 to both sides)

The new equation would be written as-

4x = x + 27

-x -x

(subtract x from both sides)


3x = 27 \\ \\ (3x)/(3) =(27)/(3) \\ \\ x=9

The number is 9

To solve for the number, we first start by setting up the equation according to the question. "27 less than four times a number is equal to the number" can be mathematically represented as:

4*x - 27 = x

where x is the number we are trying to find.

Next, we rearrange the equation to group the terms with x on one side of the equation and the constants on the other.

Subtracting x from both sides, we get

4*x - x = 27.

This simplifies to

3*x= 27

Next, we solve for x by dividing both sides of the equation by 3.

x = 27 / 3.

This gives us

x = 9

So, the number that satisfies the condition "27 less than four times a number is equal to the number" is 9.

Answer:9
