Answer 2

It looks like you've provided three different equations. Let's solve each of them step by step:

Equation 1: 8 - 5x = 13 - 3x

To solve for x, follow these steps:

1. Subtract 8 from both sides: -5x = 5 - 3x

2. Add 3x to both sides: -2x = 5

3. Divide by -2: x = -2.5

Equation 2: 2(x + 3) - 5 = 4 - (x - 9)

1. Distribute the 2 on the left side: 2x + 6 - 5 = 4 - x + 9

2. Combine like terms: 2x + 1 = 13 - x

3. Add x to both sides: 3x + 1 = 13

4. Subtract 1 from both sides: 3x = 12

5. Divide by 3: x = 4

Equation 3: 3(x + 3) = 5 - 2x

1. Distribute the 3 on the left side: 3x + 9 = 5 - 2x

2. Add 2x to both sides: 5x + 9 = 5

3. Subtract 9 from both sides: 5x = -4

4. Divide by 5: x = -0.8

So, the solutions for the given equations are:

1. x = -2.5
2. x = 4
3. x = -0.8
