Answer 2

To solve the equation 2.5(x - 6) - 7.4 = 3.5(x + 8), you can follow these steps:

1. Distribute the constants on the left side and right side of the equation to the terms in parentheses:

2.5x - 15 - 7.4 = 3.5x + 28

2. Combine like terms on both sides of the equation:

2.5x - 15 - 7.4 = 3.5x + 28 (2.5x - 7.4) - 15 = 3.5x + 28

Now, you want to isolate the x terms on one side of the equation and the constant terms on the other side.

3. Subtract 2.5x from both sides to move the x terms to the left side:

(2.5x - 7.4) - 15 - 2.5x = 3.5x - 2.5x + 28

Now, simplify the equation:

-7.4 - 15 = 28

4. Add 7.4 and 15 to both sides:

-7.4 - 15 + 7.4 + 15 = 28 + 7.4 + 15

This simplifies to:

0 = 50.4

Since 0 does not equal 50.4, there is no solution to this equation. It means that there is no value of x that will make the equation true.
