Question

(400 - m) / 7 + 80 = 130​

Answer 1

Ответ: m = 50

Пошаговое объяснение:

1) (400 - m) / 7 + 80 = 130​

2)(400 - m) / 7  = 50

3) (400 - m) = 350

4) m = 400 - 350

5) m = 50

Answer 2

To solve for the variable "m" in the equation:

(400 - m) / 7 + 80 = 130

You can follow these steps:

1. Start by isolating the fraction on the left side of the equation by subtracting 80 from both sides:

(400 - m) / 7 = 130 - 80

(400 - m) / 7 = 50

2. Now, you can eliminate the fraction by multiplying both sides of the equation by 7:

7 * ((400 - m) / 7) = 7 * 50

400 - m = 350

3. To isolate "m," subtract 400 from both sides of the equation:

400 - m - 400 = 350 - 400

-m = -50

4. Finally, multiply both sides by -1 to solve for "m":

(-1) * (-m) = (-1) * (-50)

m = 50

So, the solution to the equation is:

m = 50
