Step-by-Step Solution

To solve the equation 22x12+1612=14.5x12 22x - \frac{1}{2} + 16\frac{1}{2} = 14.5x - 12 , we will follow these steps:
1. Combine like terms on both sides of the equation.
2. Isolate the variable x x .
3. Solve for x x .

Let's start by simplifying each side:

  • Simplify the left-hand side: 22x12+1612 22x - \frac{1}{2} + 16\frac{1}{2} .

The term 1612 16\frac{1}{2} is equivalent to 16.5 16.5 , so the left-hand side becomes:
22x0.5+16.5=22x+16 22x - 0.5 + 16.5 = 22x + 16.

  • Now simplify the right-hand side: 14.5x12 14.5x - 12 .

The right-hand side remains as 14.5x12 14.5x - 12 .

Now, let's collect like terms. Move the term involving x x from the right-hand side to the left:

  • Subtract 14.5x 14.5x from both sides:
    22x+1614.5x=12 22x + 16 - 14.5x = -12

This simplifies to:
7.5x+16=12 7.5x + 16 = -12 .

Next, isolate the constant term. Subtract 16 from both sides:

  • 7.5x+1616=1216 7.5x + 16 - 16 = -12 - 16

This simplifies to:
7.5x=28 7.5x = -28 .

Finally, solve for x x by dividing both sides by 7.5:

  • x=287.5 x = \frac{-28}{7.5}

Calculating the fraction gives approximately:
x3.73 x \approx -3.73 .

Therefore, the solution to the problem is x=3.73 x = -3.73 .

Answer

3.73 -3.73
