Question

Answer 1

\(\left|2x-1\right|=32\\ \Rightarrow\left[{}\begin{matrix}2x-1=32\\2x-1=-32\end{matrix}\right.\\ \Rightarrow\left[{}\begin{matrix}2x=33\\2x=-31\end{matrix}\right.\\ \Rightarrow\left[{}\begin{matrix}x=\dfrac{33}{2}\\x=\dfrac{-31}{2}\end{matrix}\right.\)

Với \(x=\dfrac{33}{2}\) thay x= C ta có:

\(C=4x+3=4.\dfrac{33}{2}+3=2.33+3=66+3=69\)

Với \(x=\dfrac{-31}{2}\) thay x= C ta có:

\(C=4x+3=4.\dfrac{-31}{2}+3=2.\left(-31\right)+3=-62+3=-59\)
