Question

Алгебра: Система неравенств: 2x-y=-11 x-1/2+4/3=2

СабинаЛис · Answer

2х - y = - 11 ; y = 2x + 11 ; X - ( 1/2 ) + ( 4/3 ) = 2 ; X = 2 + ( 1/2 ) - ( 4/3 ) = 2 + ( 1/2 ) - 1 ( 1/3 ) = 2 + ( 3/6 ) - 1 ( 2/6 ) = 2 ( 3/6 ) - 1 ( 2/6 ) = 1 ( 1/6 ) ; Y = 2 * ( 1 ( 1/6 )) + 11 = 2 * ( 7/6 ) + 11 = ( 7/3 ) + 11 = 2 ( 1/3 ) + 11 = 13 ( 1/3 ) ; ОТВЕТ ( 1 ( 1/6 ) , 13 ( 1/3 ))...
