Question

Помогите пожалуйста ​

Answer 1

$2x - 4y = 8 \\ 2x - 4 \times 0 = 8 \\ x = 4$

$0x + 5y = - 15 \\ 0 + 5y = - 15 \\ 5y = - 15 \\ y = - 3$

$6x - 0y = 24 \\ 6x - 0 \times 0 = 24 \\ x = 4$

$3x - y = 15 \\ 3x - 0 = 15 \\ x = 5$

$a \times x - 6y = 10 \\ - 6y = 10 - a \times x \\ y = - \frac{5}{3} + \frac{1}{6} a \times x$
