x=3

Step-by-step explanation:

5/3(4x-5)=4x-1/3

20x/3 - 25/3 = 4x -1/3 add 25/3 to both sides

20x/3=4x+24/3

20x/3=4x+8 Subtract 4x from both sides

20x/3-4x=8

20x/3 - 12x/3=8

8x/3=8 multiple both sides by 3

8x=24 divide both sides by 8

x=3

Answer: $\bold{\dfrac{12\pm \sqrt{144-0}}{2(17)}}$

Step-by-step explanation:

$17x^2=12x\quad \rightarrow \quad 17x^2-12x+0=0\quad \rightarrow \quad a=17,\ b=-12,\ c=0\\\\\\\text{Quadratic formula is: }x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\\x=\dfrac{-(-12)\pm \sqrt{(-12)^2-4(17)(0)}}{2(17)}\\\\\\.\ =\dfrac{12\pm \sqrt{144-0}}{2(17)}$
