I need help with substitution

Neporo4naja [7]

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.

$2x - 1 = x - 8 \\ 2x - x = - 8 + 1 \\ x = - 7$

Substitute x = -7 in any given equations. I will choose the second equation to substitute in.

$y = x - 8 \\ y = - 7 - 8 \\ y = - 15$

Answer Check

Substitute both x and y in both equations.

$- 15 = 2( - 7) - 1 \\ - 15 = - 14 - 1 \\ - 15 = - 15$

The equation is true for (-7,-15).

$- 15 = - 7 - 8 \\ - 15 = - 15$

The second equation is true for (-7,-15).

Therefore our answer is (-7,-15)
