Question

x = 8y\
x - 4y = 12

Explanation:

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

Substitute $x=8y$ into $x-4y=12$:
$8y - 4y = 12$

Step2: Simplify to solve for $y$

Combine like terms:
$4y = 12$
Divide both sides by 4:
$y = \frac{12}{4} = 3$

Step3: Substitute $y=3$ back to find $x$

Use $x=8y$:
$x = 8\times3 = 24$

Answer:

$x=24$, $y=3$
