Question

solve for y.
2y = 5.12
y =
(there are two buttons: a back arrow and a multiplication × button on the right side of the input box)

Explanation:

Step1: Isolate y by dividing both sides

To solve for \( y \) in the equation \( 2y = 5.12 \), we divide both sides of the equation by 2. This is because we want to get \( y \) alone, and since \( y \) is multiplied by 2, we use the inverse operation (division) to isolate it. So we have:

$$ \frac{2y}{2} = \frac{5.12}{2} $$

Step2: Simplify both sides

Simplifying the left side, \( \frac{2y}{2} \) simplifies to \( y \). For the right side, we calculate \( \frac{5.12}{2} \). When we divide 5.12 by 2, we get 2.56. So:

$$ y = 2.56 $$

Answer:

\( y = 2.56 \)
