Answer:
y = 6
x = -16
Step-by-step explanation:
[tex]\left \{ {{x + 4y = 8} \atop {3x + 8y = 0}} \right.[/tex]
[tex]x + 4y = 8\\ - 4y -4y\\x = 8 - 4y\\substitution\\3(8 - 4y) + 8y = 0\\ 24 - 4y = 0\\-24 -24\\-4y = -24\\\frac{-4x}{-4} = \frac{-24}{-4}\\y = 6 \\plug \\x = 8 - 4y\\x = 8 - 4(6)\\x = -16\\y = 6, x = -16[/tex]
