Best ResponseYou've already chosen the best response.0you 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

Best ResponseYou've already chosen the best response.0\[2x/5+5x=4/3\] \[x(2/5+5)=4/3\] \[x(27/5)=4/3\] \[x=4/3*5/27\] \[x=20/81\]
