    Hint \[\large \frac{a}{bx} = c \rightarrow x= \frac{b}{a}(c)\]

    and then use 10 or 15 to multiply the 2 numbers?

    We are just asked to turn \(\large \frac{2}{3x} = 10\) into \(\large x = 15\) So we needed to isolate 'x' which can be done by...? Look at my above post

    Compare the two \[\large \frac{2}{3x} = 10 \rightarrow \frac{a}{bx} = c\] \[\large x = ?\]

    Yes we know that 'x = 15' that is given Look again what I posted, I'll copy it all at once \[\large \frac{a}{bx}=c \rightarrow x = \frac{b}{a}(c)\] You have \[\large \frac{2}{3x} = 10 \rightarrow x = \frac{?}{?}(10)\]

    i think its option A coz if you multiply 3/2 on both sides you get x=15
