16 - 2x = 5x + 9

Answer 1

To solve this equation, we need to isolate the variable x.

First, let's gather all the x terms on one side by subtracting 5x from both sides of the equation:

16 - 2x - 5x = 5x + 9 - 5x

This simplifies to:

16 - 7x = 9

Next, let's isolate the x term by subtracting 16 from both sides of the equation:

16 - 7x - 16 = 9 - 16

This simplifies to:

-7x = -7

Finally, let's solve for x by dividing both sides of the equation by -7:

-7x/-7 = -7/-7

This simplifies to:

x = 1

Therefore, the solution to the equation 16 - 2x = 5x + 9 is x = 1.
