Question

13у + 8у - 17у + 12,5 = 13,7

Answer 1

13у + 8у - 17у + 12,5 = 13,7

21у - 17у + 12,5 = 13,7

4у + 12,5 = 13,7

4у = 13,7 - 12,5

4у = 1,2

у = 0,3

Ответ: 0,3

Answer 2

$13y + 8y - 17y + 12.5 = 13.7 \\ 4y + 12 .5 = 13.7 \\ 4y = 1.2 \\ y = 0.3$

Answer 3

Let's simplify the expression step by step:

1. Combine like terms: 13у + 8у - 17у = 4у

2. Now, we have: 4у + 12.5 = 13.7

3. Subtract 12.5 from both sides of the equation to isolate the variable "у": 4у = 13.7 - 12.5 4у = 1.2

4. Finally, divide both sides by 4 to solve for "у": у = 1.2 / 4 у = 0.3

So, the solution for у is 0.3.
