Step-by-step explanation:

240=16a+4b+8c

c=3a

240=16a+4b+24a

240=40a+4b

60=10a+b

b=60-10a

a=6-b/10

x=5a+1b+3c

x=5a+60-10a+9a

x=4a+60

a=x/4+15

b=x-5a-3c

60-10a=x-5a-9a

x=60-10a+5a+9a

x=60+4a

0=60+4a-x

60=x-4a

240=16(x/4+15)+4(60-10(x/4+15))+8*3(x/4+15)

0=4x+16*15+4(60-2.5*x-150) +8x+360-240

10x-4x-8x=240+240-600+360-240

-2x=0

x=0
