Question

0,5Y - 1 - (2 Y + 4)=Y​

Answer 1

Ответ:

$0,5Y-1-(2Y+4)=Y\\0,5Y-1-2Y-4=Y\\0,5Y-2Y-Y=1+4\\-2,5Y=5\\Y=5:(-2,5)\\Y=-2$

Проверка:

$Y=-2\\0,5*(-2)-1-(2*(-2)+4)=-2\\-1-1-(-4+4)=-2\\-1-1+4-4=-2\\-2=-2$

Answer 2

To solve for Y in the equation 0.5Y - 1 - (2Y + 4) = Y, you'll need to simplify and isolate Y. Here are the steps to do that:

1. First, distribute the negative sign inside the parentheses: 0.5Y - 1 - 2Y - 4 = Y

2. Now, combine like terms on both sides of the equation. Combine the Y terms and the constants separately: (0.5Y - 2Y) - (1 + 4) = Y

3. Simplify the Y terms on the left side of the equation: -1.5Y - 5 = Y

4. Next, move the Y term on the right side to the left side by adding 1.5Y to both sides of the equation: -1.5Y - 5 + 1.5Y = Y + 1.5Y

5. Simplify the left side of the equation: -5 = 2.5Y

6. Finally, isolate Y by dividing both sides by 2.5: -5 / 2.5 = 2.5Y / 2.5

7. Simplify: -2 = Y

So, the solution to the equation is Y = -2.
