    We have been given an equation \frac{3}{5}(30x-15)=72. We are asked to choose the equations that have same value of x.    

    Let us solve our given problem.  

    \frac{3}{5}\cdot 30x-\frac{3}{5}\cdot 15=72

    3\cdot 6x-3\cdot 3=72

    18x-9=72

    Therefore, option C is the correct choice.

    Now we will factor out 3 from above equation as:

    3\cdot 6x-3\cdot 3=72

    3(6x-3)=72

    Therefore, option D is correct choice as well.

    Let us solve for x.

    \frac{3(6x-3)}{3}=\frac{72}{3}

    6x-3=24

    6x-3+3=24+3

    6x=27

    \frac{6x}{6}=\frac{27}{6}

    x=4.5

    Therefore, last option is correct as well.
