11 - 4x = -9, use the inverse order of operations or PEDMAS

Answer 1

To solve the equation 11 - 4x = -9 using the inverse order of operations (also known as the inverse of PEMDAS), we need to isolate the variable x.

First, we begin by moving the constant term from the left side to the right side of the equation by subtracting 11 from both sides:

11 - 11 - 4x = -9 - 11

This simplifies to:

-4x = -20

Next, we divide both sides of the equation by -4 to solve for x:

-4x/-4 = -20/-4

This simplifies to:

x = 5

Therefore, the solution to the equation is x = 5.
