Equation A.
Paul's plumbing: y= 40h+ 90
Perfect plumbing: y= 55h + 60
B:
Pauls plumbing: y= 40(3) + 90.... 310= y
Perfect plumbing y= 55(3) + 60... y= 225
Not the same
Answer:
No, it is not a solution
Step-by-step explanation:
Given
![x - y = 4](https://tex.z-dn.net/?f=x%20-%20y%20%3D%204)
![2x + y = 5](https://tex.z-dn.net/?f=2x%20%2B%20y%20%3D%205)
Required
Is (4,3) a solution?
(4,3) implies that: ![x = 4\ y =3](https://tex.z-dn.net/?f=x%20%3D%204%5C%20y%20%3D3)
So:
![x - y = 4](https://tex.z-dn.net/?f=x%20-%20y%20%3D%204)
![4 - 3 = 4](https://tex.z-dn.net/?f=4%20-%203%20%3D%204)
![1 \ne 4](https://tex.z-dn.net/?f=1%20%5Cne%204)
<em>Because 1 and 4 are not equal, then (4,3) is not a solution</em>
