Question
- find the value of x so that ( a parallel b ).
Step1: Igualar los ángulos alternos internos
Si \(a\parallel b\), entonces \(23x + 1=27x-19\)
Step2: Resolver para \(x\)
Restar \(23x\) de ambos lados:
\(1 = 27x-23x - 19\)
\(1=4x-19\)
Sumamos \(19\) a ambos lados:
\(1 + 19=4x\)
\(20 = 4x\)
Dividimos por \(4\):
\(x=\frac{20}{4}\)
