Question

2/9 * (2, 7 - 1 1/2 * x) - 1 1/6 * (1, 8 - 2/7 * x)

Answer 1

Ответ:

2/9(27-11/2*x)-11/6(1.8-2/7x)=-069841      x+2.7

11/2x=5.5x

2/9(27-11/2*x)-11/6(-2/7x+1.8)

2/7x=0.28571x

2/9(-5.5x+27)-11/6(-28571x+1.8)

2/9=0.22222 и.т.д

=0.22222(-5.5x+27-11/6(-0.28571x+1.8)

11/6=1.83333 и.т.д

-0.22222.(-5.5x+27) -1.83333(-0.28571x+1.8)
