Answer 2

To solve the equation (Х+12.3) / 2 = 3 * (1.5 - Х) / 2, you can start by simplifying both sides of the equation:

(Х+12.3) / 2 = 3 * (1.5 - Х) / 2

Now, you can multiply both sides of the equation by 2 to get rid of the denominators:

2 * ((Х+12.3) / 2) = 2 * (3 * (1.5 - Х) / 2)

On the left side, the 2 in the numerator and the 2 in the denominator cancel out:

Х + 12.3 = 3 * (1.5 - Х)

Now, distribute the 3 on the right side of the equation:

Х + 12.3 = 4.5 - 3Х

Next, let's isolate the variables on one side of the equation and the constants on the other side. Add 3Х to both sides of the equation:

Х + 3Х + 12.3 = 4.5 - 3Х + 3Х

This simplifies to:

4Х + 12.3 = 4.5

Now, subtract 12.3 from both sides to isolate the term with X:

4Х + 12.3 - 12.3 = 4.5 - 12.3

4Х = -7.8

Finally, divide both sides by 4 to solve for X:

4Х / 4 = -7.8 / 4

Х = -1.95

So, the solution to the equation is Х = -1.95.
