Answer 2

Let's solve the given equation step by step:

2*(y - 3.5) = 7 + 3.6*(2y - 1)

First, we simplify the equation:

2y - 7 + 7 = 7 + 7.2y - 3.6

The 7 and -7 on the left side cancel out:

2y = 7 + 7.2y - 3.6

Next, let's group the terms with y on one side:

2y - 7.2y = 7 - 3.6

Combine the y terms:

-5.2y = 3.4

Now, divide both sides of the equation by -5.2 to isolate y:

(-5.2y) / -5.2 = 3.4 / -5.2

Simplifying further:

y = -0.65

Therefore, the solution to the equation 2*(y - 3.5) = 7 + 3.6*(2y - 1) is y = -0.65.
