Answer 2

It looks like you've provided a set of equations and expressions. Let's go through them one by one:

1. Equation 1: 4x - 8 = x - 1

To solve this equation for x, you need to isolate x on one side of the equation. Here's how you can do it step by step:

Subtract x from both sides: 4x - x - 8 = x - x - 1 3x - 8 = -1

Add 8 to both sides: 3x - 8 + 8 = -1 + 8 3x = 7

Divide by 3: 3x / 3 = 7 / 3 x = 7/3 or approximately 2.33

2. Expression 1: 1:(x+2)

This is a fraction where 1 is the numerator and (x + 2) is the denominator. It can't be simplified further.

3. Expression 2: 0,9:5,4

It looks like a comma-separated list of numbers. If you meant to represent a fraction with decimal numbers, it would be written as: 0.9 / 5.4 = 0.166666... or approximately 0.167

4. Expression 3: 3:(2x-1) = 5:(3x-2)

This is a proportion. Cross-multiply and solve for x: 3 * (3x - 2) = 5 * (2x - 1) 9x - 6 = 10x - 5 Subtract 9x from both sides: -6 = x - 5 Add 5 to both sides: -1 = x

So, the solution for this proportion is x = -1.

To summarize:

1. Equation 1: x = 7/3 or approximately 2.33
2. Expression 1: 1:(x+2)
3. Expression 2: 0.167
4. Expression 3: x = -1
