according to the question
[tex] \displaystyle \: \frac{6}{17.5-x} = \frac{8 + 6}{17.5} [/tex]
simplify addition:
[tex] \displaystyle \: \frac{6}{17.5-x} = \frac{14}{17.5 } [/tex]
simplify fraction;
[tex] \displaystyle \: \frac{6}{17.5 - x} = 0.8[/tex]
cross multiplication:
[tex]\displaystyle 6 = 14 - 0.8x[/tex]
cancel 14 from both sides:
[tex] \displaystyle - 8= - 0.8x[/tex]
divide both sides by -0.8:
[tex] \therefore \: x = 10[/tex]
