Answer 2

To solve the equation 3x + 2(2.5 - 3x) = 8, you can follow these steps:

1. Distribute the 2 on the left side of the equation:

3x + 2(2.5) - 2(3x) = 8

2. Simplify:

3x + 5 - 6x = 8

3. Combine like terms by subtracting 3x from both sides of the equation:

3x - 3x + 5 - 6x = 8 - 3x

This will simplify to:

5 - 6x = 8 - 3x

4. Now, isolate the variable x. First, move the -6x term to the right side by adding 6x to both sides of the equation:

5 - 6x + 6x = 8 - 3x + 6x

This simplifies to:

5 = 8 - 3x

5. Next, move the constant term 8 to the left side by subtracting 8 from both sides of the equation:

5 - 8 = 8 - 8 - 3x

This simplifies to:

-3 = -3x

6. Finally, solve for x by dividing both sides by -3:

-3 / -3 = (-3x) / -3

This simplifies to:

1 = x

So, the solution to the equation 3x + 2(2.5 - 3x) = 8 is x = 1.
