Question

1489(а) 2,136:(1,9-х)=7,12

Answer 1

2, 136 / 1,9 - 2, 136 / х = 7,12
-2,136/ х= 7,12 - 2,136/1,9
х= (7,12-2,136/1,9)*-2,136

Answer 2

To solve the equation, we can use the following steps:

1. Multiply both sides of the equation by (1,9-х):

2,136 = 7,12(1,9-х)

2. Distribute 7,12 over (1,9-х):

2,136 = 7,12 - 7,12х

3. Add 7,12х to both sides of the equation:

2,136 + 7,12х = 7,12

4. Subtract 2,136 from both sides of the equation:

7,12х = 7,12 - 2,136

5. Simplify the right-hand side:

7,12х = 4,984

6. Divide both sides of the equation by 7,12:

х = 4,984/7,12

7. Simplify the right-hand side:

х ≈ 0,701

Therefore, the solution to the equation is х ≈ 0,701.
