solve the system by substitution.

$y = -2x$
$y = 8x - 10$

Explanation:

Step1: Substitute $y=-2x$ into second equation

$-2x = 8x - 10$

Step2: Isolate $x$ terms

$-2x - 8x = -10$
$-10x = -10$

Step3: Solve for $x$

$x = \frac{-10}{-10} = 1$

Step4: Substitute $x=1$ into $y=-2x$

$y = -2(1) = -2$

Answer:

$x=1$, $y=-2$
