Question

(3,8-y)*11=3,5*(3,6-y)

Answer 1

(3,8-y)*11=3,5*(3,6-y)

41,8 - 11y = 12,6 - 3,5y    29,2 = 7,5y      y = 3,89(3)

Answer 2

(3,8-y)*11=3,5*(3,6-y)
41,8-11y=12,6-3,5y
-11y+3,5y=12,6-41,8
-7,5y=-29,2
y=-29,2:(-7,5)
y=3 67/75

Answer 3

To solve the equation (3,8-y)11=3,5(3,6-y), we can follow these steps:

1. Distribute the multiplication on both sides of the equation: 113,8 - 11y = 3,53,6 - 3,5y

2. Simplify the products: 41,8 - 11y = 12,6 - 3,5y

3. Move all the terms containing y to one side of the equation: 41,8 - 12,6 = 11y - 3,5y 29,2 = 7,5*y

4. Solve for y by dividing both sides by 7,5: y = 29,2 / 7,5 y = 3.89 (rounded to two decimal places)

Therefore, the solution to the equation (3,8-y)11=3,5(3,6-y) is y = 3.89.
