Pull out a 5 from the first parenthesis
(5x+15) = 5(x+3)
Pull out a 25 from the second parenthesis
(25x+75) = 25(x+3)
(5x+15) + (25x+75) = your first answer = 5(x+3) + 25(x+3)
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.
