Your equation would be 3x + 5x + 7x + 9x = 240
Combine like terms and that would lead you to 24x = 240
Then divide by 24 on both side leaving you with x = 10
Plug in x and your answer would be 30:50:70:90

k2-6k4-(3k4+k2+2)

Distribua o sinal negativo:

=k2-6k4+-1(3k4+k2+2)

=k2+-6k4+-1(3k4)+-1k2+(-1)(2)

=k2+-6k4+-3k4+-k2+-2

Combine os termos semelhantes:

=k2+-6k4+-3k4+-k2+-2

=(-6k4+-3k4)+(k2+-k2)+(-2)

=-9k4+-2
