Question

3(17m-21)+5(25 -9m)=92СОЧНО​

Answer 1

Ответ:

m=5

Пошаговое объяснение:

51m-63+125-45m=92

6m+62=92

6m=92-62

6m=30

m=5

Answer 2

To solve the equation 3(17m - 21) + 5(25 - 9m) = 92, follow these steps:

1. Distribute the constants outside the parentheses to the terms inside the parentheses: 3 * 17m - 3 * 21 + 5 * 25 - 5 * 9m = 92

2. Perform the multiplications: 51m - 63 + 125 - 45m = 92

3. Combine like terms by adding or subtracting: (51m - 45m) + (-63 + 125) = 92

4. Simplify: 6m + 62 = 92

5. Now, isolate the variable m. First, subtract 62 from both sides of the equation: 6m = 92 - 62

6. Simplify the right side: 6m = 30

7. Finally, divide both sides by 6 to solve for m: m = 30 / 6 m = 5

So, the solution to the equation is m = 5.
