Step1: Use the property of same - side interior angles
When \(m\parallel n\), the sum of same - side interior angles is \(180^{\circ}\). So \((3x - 15)+(x + 7)=180\).
Step2: Simplify the left - hand side of the equation
Combine like terms: \(3x+x-15 + 7=180\), which gives \(4x-8 = 180\).
Step3: Solve for \(x\)
Add \(8\) to both sides: \(4x=180 + 8=188\). Then divide both sides by \(4\): \(x=\frac{188}{4}=47\).
