Question

solve using substitution
$y = 2x - 9$
$y = x - 1$
( , )
your answer:
(8 7 )
change my answer

Explanation:

Step1: Set equations equal

Since $y = 2x - 9$ and $y = x - 1$, substitute $y$:
$$2x - 9 = x - 1$$

Step2: Solve for $x$

Subtract $x$ and add 9 to both sides:
$$2x - x = -1 + 9$$
$$x = 8$$

Step3: Find $y$ with $x=8$

Substitute $x=8$ into $y = x - 1$:
$$y = 8 - 1 = 7$$

Answer:

$(8, 7)$
