В)x=10,8

Г)х=-18,5

Д)х=-0,15

E)x=-2,4

Жх=-1

Объяснение:

Answer 2

$a)5x = 5 - 2 \\ 5x = 3 \\ x = 3 \div 5 \\ x = \frac{3}{5} = 0.6$

б)

$2x + 2x + 1 = 0 \\ 4x = 0 - 1 \\ 4x = - 1 \\ x = - \frac{1}{4} = - 0.25$

в)

$9x - 54 = 4x \\ 9x - 4x - 54 = 0 \\ 5x - 54 = 0 \\ 5x = 54 \\ x = \frac{54}{5} = 10 \frac{4}{5} = 10.8$

г)

$30 - 6x + 8x + 7 = 0 \\ 2x + 37 = 0 \\ 2x = - 37 \\ x = - 37 \div 2 \\ x = - \frac{37}{2} = - 18 \frac{1}{2} = - 18.5$

д)

$- 2 + 20x + 8 = 3 \\ 20x + 6 = 3 \\ 20x = - 3 \\ x = - 3/20 =-0.15е)[tex]4 - 4x - 10 + 9x + 18 = 0 \\ 5x + 12 = 0 \\ 5x = - 12 \\ x = - \frac{12}{5} = - 2 \frac{2}{5} = - 2.4$

ж)

$4x + 4 - 3x - 3 = - 10 - 5x + 5 \\ x + 1 = - 5 - 5x \\ x + 1 + 5 + 5x = 0 \\ 6x + 6 = 0 \\ 6x = - 6 \\ x = - 1$
