Answer:
10
Step-by-step explanation:
1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
The last four linesof the poem reveals the solution in the poem as the first reveals the problem
If you use Desmos it'll give you these points:
(-2,0)
(-2,2)
(-2,-2)
Since it's perfectly straight line, all the points with begin with -2. It's the same for graphs like y=-2, which would make them all end in -2. Hope this helped!
