Answer 2

To solve the given equation for the variable "у," follow these steps:

Given equation: 8(2.5 – 1.5у) = 33.5 – 1.5(7 + 4у)

Step 1: Distribute the numbers on both sides of the equation to eliminate the parentheses.

On the left side: 8 * 2.5 - 8 * 1.5у = 20 - 12у

On the right side: 33.5 - 1.5 * 7 - 1.5 * 4у = 33.5 - 10.5 - 6у = 23 - 6у

So the equation becomes: 20 - 12у = 23 - 6у

Step 2: Move the terms involving "у" to one side of the equation and the constant terms to the other side.

Subtract -6у from both sides: 20 - 12у + 6у = 23 - 6у + 6у Simplify: 20 - 6у = 23

Subtract 20 from both sides: 20 - 20 - 6у = 23 - 20 Simplify: -6у = 3

Step 3: Solve for "у" by dividing both sides by -6.

Divide both sides by -6: -6у / -6 = 3 / -6 Simplify: у = -0.5

So, the solution to the equation is у = -0.5.
