X+y=15
2x+3y=37
15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8
x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7
There are 7 tricycles.

The number line in Option C.
Step-by-step explanation:
We are given an inequality.

We have to find the number line that shows the solution for the given inequality.
If we solve the given inequality,

is the required solution of the given inequality.
Thus, if we want to plot or show this solution on a number line, then we need to we need to mark the point -0.5 and all the numbers less than -0.5
A point is at negative 0.5 and a bold line starts at negative 0.5 and is pointing to the left.
This s represented in Option C.
