Answer:
p = (105-2l)/13
Step-by-step explanation:
4l + 26p = 210
Isolate 26p by subtracting 4l from both sides
26p = 210-4l now divide by 26
p = (210-4l)/26 you can simply 
p = (105-2l)/13

Ship fast equation for n packages:
2n+(1)x
where x the weight of the packages
Speedy delivery equation for the number of packages:
3n+(0.50)x
The same price happened when:
2n+(1)x = 3n+(0.50)x
x - 0.5x=3n - 2n
x = n/0.5
x = 2n
when the package weight is 2 pounds
