To solve for x, you can isolate the variable by performing the opposite operations on both sides of the equation.
Starting with the equation:
9 - 2x = -11
First, let's add 2x to both sides to isolate the constant term:
9 - 2x + 2x = -11 + 2x
This simplifies to:
9 = -11 + 2x
Now, let's add 11 to both sides to isolate the variable term:
9 + 11 = -11 + 2x + 11
This simplifies to:
20 = 2x
To solve for x, divide both sides by 2:
20/2 = 2x/2
This simplifies to:
10 = x
So the solution to the equation is x = 10.
Solve for x.
