Step-by-Step Solution

To solve this problem, we'll perform the following calculations:

  • Step 1: Multiply both sides of the equation by 52\frac{5}{2} to eliminate the fraction:

5×52=(2x2)×25×52 5 \times \frac{5}{2} = (2x - 2) \times \frac{2}{5} \times \frac{5}{2}

This simplifies to:

252=2x2 \frac{25}{2} = 2x - 2

  • Step 2: Solve for x x by isolating it on one side of the equation.
    • Add 2 to both sides to shift the constant:

    252+2=2x2+2 \frac{25}{2} + 2 = 2x - 2 + 2

    252+42=2x \frac{25}{2} + \frac{4}{2} = 2x

    292=2x \frac{29}{2} = 2x

    • Step 3: Solve for x x by dividing both sides by 2:

    x=294 x = \frac{29}{4}

    Therefore, the solution to the problem is that x=714 x = 7\frac{1}{4} .

Answer

714 7\frac{1}{4}
