Решение уравнения х+(х-у)*3-у если х=4139 у=2028 а*b+c*(a-b) если а=796 b=547 c=283 2b+m*n/7 если b=12856 m=684 n=63

Answer 1

Х + (х -у ) * 3 - у, если х=4139, у=2028
4139+(4139-2028)*3-2028
4139+6333-2028= 8444

а * b + с * (а - b), если а= 796,b=547,с=283
796*547+283*(796-547)
435412+70467=505879

2b + m * n :7, если b=12856,m=684,n=63
2*12856+684*9
25712+6156=31868

Answer 2

To solve the given equations, simply substitute the given values of variables and perform the calculations step by step. Let's solve each equation one by one:

1. х + (х - у) * 3 - у, where х = 4139, у = 2028: Plug in the values and calculate:

   х + (х - у) * 3 - у = 4139 + (4139 - 2028) * 3 - 2028 = 4139 + (2111) * 3 - 2028 = 4139 + 6333 - 2028 = 8444

   The solution for this equation is 8444.

2. a * b + c * (a - b), where a = 796, b = 547, c = 283: Plug in the values and calculate:

   a * b + c * (a - b) = 796 * 547 + 283 * (796 - 547) = 435412 + 283 * 249 = 435412 + 70467 = 505879

   The solution for this equation is 505879.

3. 2b + m * n / 7, where b = 12856, m = 684, n = 63: Plug in the values and calculate:

   2b + m * n / 7 = 2 * 12856 + 684 * 63 / 7 = 25712 + 43092 / 7 = 25712 + 6156 = 31868

   The solution for this equation is 31868.

So, the solutions to the given equations are as follows:

1. х + (х - у) * 3 - у = 8444
2. a * b + c * (a - b) = 505879
3. 2b + m * n / 7 = 31868
