Answer 3

To solve the equation 7у - 12у + 20 = 2 - 12у - 27, we can simplify and combine like terms on both sides of the equation.

Starting with the left side of the equation: 7у - 12у + 20 simplifies to -5у + 20.

Moving to the right side of the equation: 2 - 12у - 27 simplifies to -25 - 12у.

Now we can rewrite the equation with the simplified terms: -5у + 20 = -25 - 12у.

To solve for у, we'll isolate the у term on one side of the equation. Let's add 12у to both sides: -5у + 12у + 20 = -25 - 12у + 12у.

Simplifying the equation further: 7у + 20 = -25.

Next, let's move the constant term (20) to the right side by subtracting 20 from both sides: 7у + 20 - 20 = -25 - 20.

Simplifying: 7у = -45.

Finally, we can solve for у by dividing both sides of the equation by 7: (7у)/7 = -45/7.

Simplifying: у = -45/7.

Therefore, the solution to the equation is у = -45/7.
