Identify the given value and the equation: the value to verify is \(y = -2\), and the equation is \(5y + 4 = 14\).
Substitute the given value \(y = -2\) into the equation by replacing every \(y\) with \(-2\), resulting in \(5(-2) + 4 = 14\).
Simplify the left side of the equation: multiply \(5\) by \(-2\) to get \(-10\), so the expression becomes \(-10 + 4\).
Add \(-10\) and \(4\) to simplify the left side further, which gives \(-6\).
Compare the simplified left side \(-6\) with the right side \(14\); since they are not equal, conclude that \(y = -2\) is not a solution to the equation.
