Solve for x.

9−2x=−11

x =

1 answer

To solve for x, we need to isolate the variable x on one side of the equation.

First, we can start by adding 2x to both sides of the equation to get rid of the -2x term on the left side:

9 - 2x + 2x = -11 + 2x

Simplifying this equation, we get:

9 = -11 + 2x

Next, we can subtract -11 from both sides of the equation to get rid of the constant term on the right side:

9 - (-11) = -11 + 2x - (-11)

Simplifying this equation, we get:

9 + 11 = 2x

20 = 2x

Finally, we can divide both sides of the equation by 2 to solve for x:

20/2 = 2x/2

10 = x

Therefore, x = 10 is the solution to the equation.
