PLEASE I NEED HELP

Answer 1

let mass of truck be t
mass of car A be a
and carB be b

so , a=2b-5
t=a+2135

putting a into t...
t=2b-5+2135

so, a+b+t=11350 ( putting all values)
2b-5+b+2b-5+2135=11350

so b=1845
a=3685
t=5820

so weight of Car A is 3685 lb
weight of Car B is 1845 lb
and truck is 5820 lb ......answers !!
