Question

1-0,5*(1-у)= -0,2*(у+1)

Answer 1

Ответ:

Пошаговое объяснение:

1-0,5*(1-у)= -0,2*(у+1)

1-0.5+0.5у=-0.2у-0.2

0.5у+0.2у=-0.2+0.5-1

0.7у=-0.7

у=-0.7:0.7

у=-1

Answer 2

To solve the equation 1 - 0.5*(1 - y) = -0.2*(y + 1), you'll need to find the value of y that satisfies the equation. Let's go step-by-step:

Step 1: Distribute the terms on the right side of the equation: 1 - 0.5 + 0.5y = -0.2y - 0.2

Step 2: Combine like terms: 0.5y + 0.5 = -0.2y - 0.2

Step 3: Move all y terms to one side of the equation by adding 0.2y to both sides: 0.5y + 0.2y + 0.5 = -0.2y + 0.2y - 0.2

Step 4: Simplify: 0.7y + 0.5 = -0.2

Step 5: Move the constant term to the other side of the equation by subtracting 0.5 from both sides: 0.7y = -0.2 - 0.5

Step 6: Simplify: 0.7y = -0.7

Step 7: Isolate y by dividing both sides by 0.7: y = -0.7 / 0.7

Step 8: Final answer: y = -1

So the solution to the equation is y = -1.
