Answer 1

$2x - y = 2 \ 3x - 2y = 3 \ \ 4x - 2y = 4 \ 3x - 2y = 3 \ \ x = 1 \ y = 2x - 2 \ \ x = 1 \ y = 0$
Ответ: (1; 0)

2)
$frac{x}{3} - frac{y}{2} = - 4 \ frac{x}{2} + frac{y}{4} = - 2 \ \ 2x - 3y = - 24 \ 2x + y = - 8 \ \ 4y = 16 \ 2x = - 8 - y \ \ y = 4 \ 2x = - 12 \ \ y = 4 \ x = - 6$
Ответ: (-6; 4)

3)
$2 - 3x = 2(1 - y) \ 4(x + y) = x - 1.5 \ \ 2 - 3x = 2 - 2y \ 4x + 4y = x - 1.5 \ \ - 3x + 2y = 0 \ 4x - x + 4y = - 1.5 \ \ 3x - 2y = 0 \ 3x + 4y = - 1.5 \ \ 6y = - 1.5 \ 3x = 2y \ \ y = - 0.25 \ 3x = - 0.5 \ \ y = - 0.25 \ x = - 0.5 div 3 = - frac{1}{6}$
Ответ: (-1/6; -0,25)
