Question

-15 = -19 + \frac{1}{2}y

Explanation:

Step1: Add 19 to both sides

To isolate the term with \( y \), we add 19 to both sides of the equation \(-15 = -19+\frac{1}{2}y\).
\[
-15 + 19=-19 + 19+\frac{1}{2}y
\]
Simplifying the left - hand side and the right - hand side, we get \(4=\frac{1}{2}y\).

Step2: Multiply both sides by 2

To solve for \( y \), we multiply both sides of the equation \(4=\frac{1}{2}y\) by 2.
\[
4\times2=\frac{1}{2}y\times2
\]
Simplifying both sides, we find that \(y = 8\).

Answer:

\(y = 8\)
