-19/105x + 19/135

Explanation:

Consider:" "color(blue)((-2/9x-1/5))color(brown)((3/7x-1/3))

Multiply everything inside the right hand bracket by everything in the left.

Note that the signs follow the values they are assigned to

color(brown)(color(blue)( -2/9)(3/7x-1/3) color(blue)(" "-1/5)(3/7x-1/3) )

-2/21x+2/27 " "-3/35x+1/15

-19/105x + 19/135
