Question

1) 25-3в=9-5в 2)12-2к+3=26

Answer 1

1) 25-3в=9-5в
-3в+5в=9-25
2в=-16
в=-8

2) 12-2к+3=26
-2к=26-12-3
-2к=11
к=-5.5

Answer 2

-3в+5в=-25+9
2в=-16
в=-8


-2к=-12-3+26
-2к=11
к=-5 1/2

Answer 3

To solve the equations, we need to find the values of the variables "в" and "к". Let's solve them step by step:

1. 25 - 3в = 9 - 5в

First, let's isolate the variable "в" on one side of the equation. To do this, we'll move all the terms containing "в" to one side and the constants to the other side:

25 - 9 = 5в - 3в

Simplifying both sides:

16 = 2в

Now, divide both sides by 2 to solve for "в":

в = 16 / 2 в = 8

So, the value of "в" is 8.

2. 12 - 2к + 3 = 26

Let's simplify the equation:

15 - 2к = 26

Now, let's isolate the variable "к" on one side:

-2к = 26 - 15 -2к = 11

Finally, divide both sides by -2 to solve for "к":

к = 11 / -2 к = -5.5

So, the value of "к" is -5.5.

Therefore, the solutions to the equations are:

1. в = 8
2. к = -5.5
