Question

the value of y.
3y
5y - 14

Explanation:

Step1: Use the property of isosceles triangle

In an isosceles triangle, the two base angles are equal, so the sides opposite to them are equal. Here, \(3y = 5y - 14\).

Step2: Solve the equation

Subtract \(3y\) from both sides: \(0=5y - 14 - 3y\), which simplifies to \(0 = 2y-14\).
Add \(14\) to both sides: \(14=2y\).
Divide both sides by \(2\): \(y = 7\).

Answer:

\(7\)
