Question

George and carmen went on a bicycle trip. they took a bus to their starting point, then biked the rest of the way. they traveled 300 kilometers in total, and they biked 70 kilometers more than they were bussed.

let x= kilometers traveled by bike
let y= kilometers traveled by bus

Answer 1

Ok so we know that x = y+70
So y+y+70 = 300
2y+70 = 300
2y = 230
y = 115
So we know that x = y+70
do x = 115+70
X= 185
