Question

Please help me. I’m stuck on it

Answer 1

y = 6

x = -16

Explanation:

`\left \{ {{x + 4y = 8} \atop {3x + 8y = 0}} \right.`

`x + 4y = 8\\ - 4y -4y\\x = 8 - 4y\\substitution\\3(8 - 4y) + 8y = 0\\ 24 - 4y = 0\\-24 -24\\-4y = -24\\(-4x)/(-4) = (-24)/(-4)\\y = 6 \\plug \\x = 8 - 4y\\x = 8 - 4(6)\\x = -16\\y = 6, x = -16`
