To solve this problem, we'll follow these steps:
- Step 1: Subtract 13 from both sides of the equation to isolate the term with x.
- Step 2: Divide by −2 to solve for x.
Now, let's work through each step:
Step 1: Begin by subtracting 13 from both sides:
13−2x−13=0−13
Which simplifies to:
−2x=−13
Step 2: Divide both sides by −2 to solve for x:
−2−2x=−2−13
This simplifies to:
x=213
When expressed as a mixed number, x equals:
x=621.
Therefore, the solution to the problem is x=621.
The correct answer choice is : x=621
.
x=621
