Question 515072
You're not confused.  If two functions have the
same solution the graphs of those functions
meet at the point of the solution.
------------------------
y = 2x+3
y = x -4
---
2x+3 = x-4
x = -7
---
Solve for "y":
y = x-4
y = -7-4 = -11
y = -11
Solution: (-7,-11)
{{{graph(400,400,-15,5,-15,5,2x+3,x-4)}}}
