Question

При Якому значенні m 4-2m=7?

Answer 1

Ответ:

m=-1,5.

Пошаговое объяснение:

4-2m=7

-2m=7-4

-2m=3

m=3:(-2)

m=-1,5.

Answer 2

To find the value of m in the equation 4 - 2m = 7, follow these steps:

Step 1: Move the constant term to one side of the equation.

Add 2m to both sides of the equation: 4 - 2m + 2m = 7 + 2m

This simplifies to: 4 = 7 + 2m

Step 2: Move the constant term to the other side of the equation.

Subtract 7 from both sides of the equation: 4 - 7 = 7 + 2m - 7

This simplifies to: -3 = 2m

Step 3: Solve for m.

To find the value of m, divide both sides of the equation by 2: -3 / 2 = 2m / 2

This simplifies to: m = -3/2

So, the value of m is -3/2 or -1.5.
