Question

0,12+0,8x=-0,08 решить уравнения

Answer 1

0,8x=-0,08-0,12

0,8x=-0,2

x=-0,25

Answer 2

To solve the equation 0.12 + 0.8x = -0.08, follow these steps:

Step 1: Move the constant term to the other side of the equation. Subtract 0.12 from both sides of the equation: 0.12 + 0.8x - 0.12 = -0.08 - 0.12

This simplifies to: 0.8x = -0.2

Step 2: Isolate the variable x. To do this, divide both sides by 0.8: 0.8x / 0.8 = -0.2 / 0.8

This simplifies to: x = -0.25

Step 3: Check your answer. To confirm that the solution is correct, substitute the value of x back into the original equation: 0.12 + 0.8(-0.25) = -0.08

This simplifies to: 0.12 - 0.2 = -0.08

Which further simplifies to: -0.08 = -0.08

Since both sides are equal, the solution x = -0.25 is correct.
