Answer:

-16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

Answer:

x = - 16

Step-by-step explanation:

Let the number = x

Read the phrases just a little at a time.

  • "four times a number"
  • 4x
  • "Twenty One Less than"
  • 4x - 21

is which means =

  • "six times the number"
  • 6x
  • "plus 11"
  • 6x + 11

So put the two parts together.

Equation

4x - 21 = 6x + 11                   Add 21 to both sides

Solution

4x - 21 + 21 = 6x + 11 + 21    Combine

4x = 6x + 32                         Subtract 6x from both sides.

4x - 6x = 6x - 6x + 32          Combine

- 2x = 32                               Divide by -2

-2x/-2 = 32/-2

x = -16
