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

Answer:
[tex]x = 48 \: \: \: \: \: \: y = 16[/tex]
Step-by-step explanation:
[tex]y = - x + 4y[/tex]
[tex]y + x = 4y[/tex]
[tex]y + x - 4y = 0[/tex]
[tex] - 3y + x = 0[/tex]
[tex] - x + 4y = 16[/tex]
[tex] - 3y + x = 0[/tex]
[tex] - 3y = - x[/tex]
[tex]y = - \frac{1}{3} ( - 1)x[/tex]
[tex]y = \frac{1}{3} x[/tex]
[tex]4 \times ( \frac{1}{3} )x - x = 16[/tex]
[tex] \frac{1}{3}x = 16 [/tex]
[tex]x = 48[/tex]
[tex]y = \frac{1}{3} \times 48[/tex]
[tex]y = 16[/tex]
Hope this is correct and helpful
HAVE A GOOD DAY!
