Answer:
[9, 13]
Step-by-step explanation:
{y = x + 4
{y = 2x - 5
Since we have two expressions set equal to y, use the Substitution Method:
[tex]x + 4 = 2x - 5[/tex]
-2x -2x
___________________
-x + 4 = -5
- 4 - 4
__________
-x = -9
x = 9 [Plug this back into both equations to get the y-coordinate of 13]; 13 = y
