Sherina made a mistake by incorrectly simplifying the equation. When she subtracted 24 from both sides of the equation \(y - 24 = 133\), she should have calculated \(133 - 24\) correctly, arriving at \(y - 24 = 109\), but she failed to express the final computation correctly in her steps.
-
To solve this problem correctly, Sherina should have subtracted 24 from both sides of the equation and properly calculated the result. So, starting from \(y - 24 = 133\), she should have done: \[ y - 24 - 24 = 133 - 24 \] Simplifying gives: \[ y = 133 - 24 \] which leads to: \[ y = 109 \] Therefore, it is important to ensure that all arithmetic operations are performed accurately.
-
The correct final answer for the value of \(y\) is \(109\).
