Question

1.
а)5x + 1 = 0
б)5x - 6 = x - 14
в)2/3 (6x - 3) = 8 - (5x + 1)
2.
а)2x - 1 = 0
б)x + 9 = 4x + 3
в)3/4 (4x + 8) = 9 - (7x - 1)

Answer 1

1.а) 5x= -1 /:5, x= -0,2
б) 5x-x= -14 + 6, 4x = - 8/:4 , x= -2
2. а) 2x= 1/:2, x= 0,5
б) x-4 x = 3-9, -3x= -3/:(-3), x=1

Comments

Простите,а что означает: "-1 /:5","- 8/:4","1/:2" и "-3/:(-3)"?
