Answer 3

To solve the equation "3x - 20 = 55," you need to isolate the variable "x" on one side of the equation. Here's how you can do it step by step:

1. Add 20 to both sides of the equation to get rid of the constant term (-20) on the left side: 3x - 20 + 20 = 55 + 20

Simplified equation: 3x = 75

2. Now, you need to solve for "x." To do this, divide both sides of the equation by 3: 3x / 3 = 75 / 3

Simplified equation: x = 25

So, the solution to the equation is x = 25.
