- X = - 21 - ( - 44 )
- X = - 21 + 44
- X = 23
X = - 23
Ответ 2) ( - 23 )
----------------------------
2*( 3X - 1) - 4*( 2X + 3 ) = 6X - 2 - 8X - 12 = - 2X - 14
Ответ 4) - 2Х - 14
-----------------------------------
(3X +8)*( 8X - 1 ) = 0
3X + 8 = 0
X = - 8/3 = - 2 2/3
8X - 1 = 0
X = 1/8
Ответ 4) - 2 2/3 и 1/8
---------------------------------------
4*( X - 1) - 3*( X + 2 ) = 6
4X - 4 - 3X - 6 = 6
X - 10 = 6
X = 16
Ответ 2) 16
