question
solve the system by substitution.
$y = 8x$
$y = 4x + 8$

Explanation:

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

$8x = 4x + 8$

Step2: Isolate $x$ term

$8x - 4x = 8$
$4x = 8$

Step3: Solve for $x$

$x = \frac{8}{4} = 2$

Step4: Substitute $x=2$ into $y=8x$

$y = 8\times2 = 16$

Answer:

$x=2$, $y=16$
