Question

George and Karmen went on a bike trip. They took a bus to their starting point, and then biked the rest. They traveled 350 kilometers in total, and they biked 80 kilometers more than they were bussed.

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

Answer 1

Find how many kilometers they traveled by bike

Answer 3

You can set up as:
x + y = 350.. the distance travelled is 350 in total
y + 80 = x ... since the amount done by bike is 80 more than the bus

Answer 4

Ok so what should i do to get x and y?

Answer 5

You can sole each equation for x (or y if you wanted), then substitute what x is equal into the other equation...
Like:
x + a = y
-x + -y = 2

Then you can do
x = y - a
and
x = -y - 2

then equate both equations:
y - a = -y -2

Answer 6

can solve*

Answer 7

Haha im sorry.. youre explaining it well its just im confused. Im not very good with equations.

Answer 8

Ok don't worry :) One step at a time..
First, are you able to solve each equation for x (meaning, isolate your x variable so that only one x is on one side of the equals sign... like " x = ... " )

Answer 9

Ummm it all depends on the equation. But on this one i wouldnt know how

Answer 10

For the second equation, your x is already on one side
y + 80 = x
same as:
x = y + 80

Answer 11

For the 1st equation:
x + y = 350
you can subtract y from both sides, this will get rid of the y on the right side, and leave x only

Answer 12

ok

Answer 13

what do you get

Answer 14

x=350 right..

Answer 15

not quite, you have to subtract y on both sides.. so you should have:
x = 350 - y

Answer 16

I have 3 min do you know what the answer is??
