Answer:

$112

Step-by-step explanation:

First you must see that there are 2 variables in this problem, the bike and accesories.

If the bike and accesories are equal to $140 then, x+y=140.

If the bike is 4x the amount of the accesories then 4x=y. Substitute y in the first equasion for x+4x=140.

That means 5x=140, and solving for x you get $28. Since the bike was 4x the amount of accesories then 4*28= $112.

To check your work you can solve it again. $28+$112=$140 or 28+4*28=140.

ANTONII [103]

We are given

First equation:

y=x-1

we can use formula

y=mx+b

slope is m=1

y-intercept is b=-1

Second equation:

y=-2x+5

we can use formula

y=mx+b

slope is m=-2

y-intercept is b=5

Graph:

We can see that

both curves intersect at (2,1)

so, solution is x=2 and y=1.................Answer
