Kilometers of the journey

A cyclist traveled 199 km in three days. On the first day, he traveled four times more than on the second day and on the second day, he traveled 7 km less than on the third day. How many kilometers did he travel each day?

Correct answer:

a =  128 km
b =  32 km
c =  39 km

Step-by-step explanation:

a+b+c=199 a=4b b=c7  4b+b+(b+7)=199  4 b+b+(b+7)=199  6b=192  b=6192=32  b=32  a=4 b=4 32=128 km
