Answer 1

5)

$x -2 y = 24 \\ 4x - 3y = 16 \\ \\ x = 24 + 2y \\ 4(24 + 2y) - 3y = 16 \\ \\ 96 + 8y - 3y = 16 \\ 5y = 16 - 96 \\ 5y = - 80 \\ y = - 80 \div 5 \\ y = - 16 \\ \\ x = 24 + 2 \times ( - 16) = 24 - 32 = - 8$

Ответ: ( - 8 ; - 16 )

6)

$3x + 2y = 10 \\ x - 4y = 1 \\ \\ 3(4y + 1) + 2y = 10 \\ x = 4y + 1 \\ \\ 12y + 3 + 2y = 10 \\ 14y = 10 - 3 \\ 14y = 7 \\ y = 7 \div 14 \\ y = 0.5 \\ x = 4 \times 0.5 + 1 = 2 + 1 = 3$

Ответ: (3 ; 0,5 )
