In one day, Annie traveled 5 times the sum of the number of hours Brian traveled and 3. Together they traveled 30 hours. Find the number of hours each person traveled.
a is 5 times of b and 3 means a=5(b+3) together travel 30 a+b=30
so sub 5(b+3) for a 5(b+3)+b=30 distribute 5b+15+b=30 6b+15=30 minus 15 both sides 6b=15 divide boh sides by 6 b=2.5 sub back a=5(b+3) a=5(2.5+3) a=5(5.5) a=27.5
annie traveled 27.5 hours brian traveled 2.5 hours
