Question

6*(2,3х-1)-3,5х+0,7х=0,5(х-14)

Answer 1

13,8х-6-3,5х+0,7х=0,5х-7

13,8х-3,5х+0,7х-0,5х=6-7

10,5х=-1

х=-1/10,5

х=-0,095

Answer 2

Ответ:

x = $-\frac{2}{21}$

Объяснение:

6(2,3x - 1) - 3,5x + 0,7x = 0,5(x - 14)

13,8x - 6 - 3,5x + 0,7x = 0,5x - 7

11x - 6 = 0,5x - 7

11x - 0,5x = -7 + 6

10,5x = -1

x = $-\frac{2}{21}$
