Question
find the value of x for which ( j parallel m ).
a. 24
b. 26
c. 12.75
d. 14
Step1: Angulos alternos internos
Como \(j\parallel m\), entonces \(5x - 20 = 3x + 28\) (ángulos alternos internos).
Step2: Resolver la ecuación
Restar \(3x\) de ambos lados: \(5x-3x - 20=3x - 3x+ 28\), es decir \(2x-20 = 28\).
Step3: Sumar 20 a ambos lados
\(2x-20 + 20=28 + 20\), entonces \(2x=48\).
Step4: Dividir por 2
\(x=\frac{48}{2}\).
