Question

(0.8 - х) : 1.5 = 4.2

Answer 1

Ответ:

0.8 - х = 4.2 * 1.5

0.8 - х = 6.3

х = 6.3 - 0.8

х = 5.5

x = -5.5

Answer 2

To solve the equation (0.8 - x) / 1.5 = 4.2, we can start by isolating the variable x.

First, multiply both sides of the equation by 1.5 to get rid of the fraction:

1.5 * (0.8 - x) / 1.5 = 4.2 * 1.5

This simplifies to:

0.8 - x = 6.3

Next, subtract 0.8 from both sides of the equation:

0.8 - x - 0.8 = 6.3 - 0.8

This simplifies to:

-x = 5.5

To solve for x, multiply both sides of the equation by -1 to change the sign:

(-1) * (-x) = (-1) * 5.5

This gives us:

x = -5.5

Therefore, the solution to the equation (0.8 - x) / 1.5 = 4.2 is x = -5.5.
