Solve the system using substitutions:

x has a value of 1. Use this value to find the value of y.

y has a value of 1.
x=1
y=1
I think 1 is A , I think!
If C is between A and B, then, we can write the equation

Substitute the value of AB and the expressions for AC and CB in terms of x.

We can now solve for x.


Dividing by 5.
