$y = -7x - 30$
$y = 8x$

answer attempt 1 out of 3
(\boxed{1}, \boxed{\space})$ submit answer

Explanation:

Step1: Substitute $y=8x$ into first equation

$8x = -7x - 30$

Step2: Isolate $x$ terms

$8x + 7x = -30$
$15x = -30$

Step3: Solve for $x$

$x = \frac{-30}{15} = -2$

Step4: Solve for $y$ using $y=8x$

$y = 8\times(-2) = -16$

Answer:

$(-2, -16)$
