I need help, I don’t need an explanation, just the answer

meriva

Answer:

$x = 48 \: \: \: \: \: \: y = 16$

Step-by-step explanation:

$y = - x + 4y$

$y + x = 4y$

$y + x - 4y = 0$

$- 3y + x = 0$

$- x + 4y = 16$

$- 3y + x = 0$

$- 3y = - x$

$y = - \frac{1}{3} ( - 1)x$

$y = \frac{1}{3} x$

$4 \times ( \frac{1}{3} )x - x = 16$

$\frac{1}{3}x = 16$

$x = 48$

$y = \frac{1}{3} \times 48$

$y = 16$

Hope this is correct and helpful
