x/60=((3950-x)/45)+8.1 Is the thing that is giving me problems.

x/60=((3950-x)/45)+8.1

 

Multiply through by the common denominator of 45, 60  =  180

 

So we have

 

3x  = 4(3950 - x)  + 1458     simplify

 

3x  =  15800 -  4x + 1458     add 4x to both sides and simplify the right side

 

7x  = 17528    divide both sides by 7

 

x ≈ 2465.43

 

 

cool cool cool

Ok, I just wanted to make sure that I was doing the right thing that's all.
