Answer:
(-7,-15)
Step-by-step explanation:
We can substitute first y in the second y. Both equations are also functions. We can merge the equations.
[tex]2x - 1 = x - 8 \\ 2x - x = - 8 + 1 \\ x = - 7[/tex]
Substitute x = -7 in any given equations. I will choose the second equation to substitute in.
[tex]y = x - 8 \\ y = - 7 - 8 \\ y = - 15[/tex]
Answer Check
Substitute both x and y in both equations.
[tex] - 15 = 2( - 7) - 1 \\ - 15 = - 14 - 1 \\ - 15 = - 15[/tex]
The equation is true for (-7,-15).
[tex] - 15 = - 7 - 8 \\ - 15 = - 15[/tex]
The second equation is true for (-7,-15).
Therefore our answer is (-7,-15)
