    \[2x/5+5x=4/3\] \\[[x(2/5+5)=4/3\]\]

    Where did you get the x=20? by 4*5?

    you can simplify this equation by multiplying each side by 3: 6x/(5+5x)=4 factor out a 5 in the denominator: 6x/(5(1+x))=4 multiply both sides by 5: 6x/(1+x)=20 multiply by (1+x): 6x=20+20x subtract 20x: 6x -20x=20 -14x=20 divide by -14 x=20/-14=-10/7

    \[2x/5+5x=4/3\] \[x(2/5+5)=4/3\] \[x(27/5)=4/3\] \[x=4/3*5/27\] \[x=20/81\]
