Question

13(9m+6)+9(7-12m)=681

Answer 1

Ответ:

M=60

Пошаговое объяснение:

117m+78+63=681

9m+78+63=681

9m+141=681

9m=681-141

9m=540

M=540:9

M=60

Answer 2

Пошаговое объяснение:

13 * 9m + 13 * 6 + 9*7 - 9 * 12m=681

117m + 78+63-108m=681

9m+141=681

9m=681-141

9m=540

m=540:9

m=60

Answer 3

To solve the equation $13(9m+6)+9(7-12m)=681$, follow these steps:

Step 1: Distribute the constants outside the parentheses: $117m + 78 + 63 - 108m = 681$

Step 2: Combine like terms on both sides of the equation: $117m - 108m + 78 + 63 = 681$ $9m + 141 = 681$

Step 3: Subtract 141 from both sides of the equation to isolate the term with $m$: $9m = 540$

Step 4: Divide both sides by 9 to solve for $m$: $m = \frac{540}{9}$ $m = 60$

So, the solution to the equation is $m = 60$.
