Question

2 • (у - 3,5) = 7 + 3,6 • (2у - 1).

Answer 1

2*(у-3,5)=7+3,6*(2у-1)
2у-7=7+7,2у-3,6
2у-7,2у=7+7-3,6
-5,2у=10,4
у=10,4:(-5,2)
у=-2

Answer 2

2y-7=7+7,2y-3,6
2y-7,2y=7-3,6+7
-5,2y=10,4
y=-2

Answer 3

Let's solve the equation step by step:

2 * (у - 3.5) = 7 + 3.6 * (2у - 1)

First, we'll distribute the multiplication:

2у - 7 + 3.6 * 2у - 3.6 = 7 + 3.6 * 2у - 3.6

Simplifying further:

2у - 7 + 7.2у - 3.6 = 7.2у - 3.6

Combining like terms:

2у + 7.2у - 7.2 = 7.2у - 3.6

9.2у - 7.2 = 7.2у - 3.6

Next, we'll isolate the у terms on one side and the constant terms on the other side:

9.2у - 7.2у = -3.6 + 7.2

1.6у = 3.6

Finally, we'll solve for у by dividing both sides by 1.6:

у = 3.6 / 1.6

у = 2.25

Therefore, the solution to the equation is у = 2.25.
