Question

Розв'яжи рiвняння.
a) [x] = 1,5;
6) [x] = -0,1;
в) [4x - 1] = 9;
r) [10,04x +4] = 4,08.​

Answer 1

Ответ:

1) (х) = 1,5;

х = 1,5;

10х = 15;

2х = 3;

2) (х) = - 0,1;

х = - 0,1;

10х = 10 × ( - 0,1);

10х = - 1;

3) (4х - 1) = 9;

4х - 1 = 9;

4х = 9 + 1;

4х = 10; /:

2х = 5;

4) (10,04х + 4) = 4,08;

10,04х + 4 = 4,08;

10,04х = 4,08 - 4;

10,04х = 0,08;

1004х = 8;

251х = 2;
