Question

Уравнение 4,2•(1-m)=-8,4

Answer 1

Ответ:

Пошаговое объяснение:

4,2 * (1 - m) = - 8.4

4.2 - 4.2m = - 8.4

4.2m = 4.2 - (-8.4)

4.2m = 12.6

m = 12.6 : 4.2

m = 3

Answer 2

To solve the equation 4.2•(1-m) = -8.4, follow these steps:

Step 1: Distribute the 4.2 on the left side of the equation:

4.2 • 1 - 4.2 • m = -8.4

Step 2: Simplify the equation:

4.2 - 4.2m = -8.4

Step 3: Move all the terms containing 'm' to one side of the equation by adding 4.2m to both sides:

4.2m = 4.2 - 8.4

Step 4: Simplify the right side:

4.2m = -4.2

Step 5: Finally, isolate 'm' by dividing both sides by 4.2:

m = -4.2 / 4.2

m = -1

So, the solution to the equation is m = -1.
