solve for x.
9-2x=-11
To solve for x, we need to isolate x on one side of the equation.
To do this, we first add 2x to both sides of the equation:
9 - 2x + 2x = -11 + 2x
This simplifies to:
9 = -11 + 2x
Next, we combine like terms on the right side:
9 = 2x - 11
To isolate x, we add 11 to both sides of the equation:
9 + 11 = 2x - 11 + 11
This simplifies to:
20 = 2x
Finally, we divide both sides of the equation by 2 to solve for x:
20/2 = 2x/2
This simplifies to:
10 = x
Therefore, the solution to the equation 9-2x = -11 is x = 10.
To solve for x in the equation 9 - 2x = -11, follow these steps:
Step 1: Start with the given equation: 9 - 2x = -11.
Step 2: Subtract 9 from both sides of the equation to isolate the variable term: 9 - 2x - 9 = -11 - 9.
Simplifying, we get -2x = -20.
Step 3: Divide both sides of the equation by -2 to solve for x: (-2x) / -2 = -20 / -2.
Simplifying, we get x = 10.
Therefore, the solution to the equation 9 - 2x = -11 is x = 10.
To solve for x in the equation 9-2x=-11, you need to isolate the variable x by performing some algebraic operations. Here's how you can do it step by step:
1. Start by moving the constant term (-11) to the other side of the equation by adding 11 to both sides:
9 - 2x + 11 = -11 + 11
Simplifying both sides of the equation gives:
20 - 2x = 0
2. Now, you want to isolate the term with x. To eliminate the constant term on the left side, subtract 20 from both sides:
20 - 2x - 20 = 0 - 20
Simplifying both sides of the equation gives:
-2x = -20
3. Since you want to solve for x, divide both sides of the equation by -2:
(-2x) / -2 = (-20) / -2
Simplifying both sides of the equation gives:
x = 10
So, the solution to the equation 9-2x=-11 is x = 10.
