Пошаговое объяснение:
4x - 2/3y + 3 2/3 = 0
4x + 3 1/3y - 1/3 = 0
------------------------------
4x - 2/3y + 3 2/3 - 4x - 3 1/3 + 1/3 = 0
-2/3y + 3 2/3 - 3 1/3y + 1/3 = 0
-4y + 4 = 0
-4y = -4
y = 1
--------------------------------
4x - 2/3 + 3 2/3 = 0
4× + 3 = 0
4x = -3
x = -3/4 = -0,75
Ответ:
x = -0,75; y = 1
