To solve the equation 5x – 8 = 3x + 10, we’ll start by isolating the variable x. Here are the steps:
- First, move the terms involving x to one side of the equation. We can do this by subtracting 3x from both sides:
- This simplifies to:
- Next, add 8 to both sides to get rid of the -8:
- Which simplifies to:
- Now, divide both sides by 2 to isolate x:
- Thus, the solution is:
5x – 3x – 8 = 10
2x – 8 = 10
2x – 8 + 8 = 10 + 8
2x = 18
x = 18 / 2
x = 9
We’ve now solved the equation! The answer is x = 9.
