x =
submit answer
Step1: Identificar ángulos alternos internos
Como \( m\parallel n \), entonces \( 6x + 9 = 5x+16 \) (ángulos alternos internos son iguales).
Step2: Resolver la ecuación
Restar \( 5x \) de ambos lados: \( 6x - 5x+9=5x - 5x + 16 \), lo que da \( x+9 = 16 \).
Restar \( 9 \) de ambos lados: \( x+9 - 9=16 - 9 \), entonces \( x = 7 \).
