Question

|4x + 1| = 6

Answer 1

\[\left| 4x+1 \right|=6\]Eliminate the absolute value:
\[4x+1=6\] or \[4x+1=-6\]
In the first equation, subtract one from both sides.\[4x=5\]Divide by four.\[x=\frac{ 5 }{ 4 }\]
In the second, subtract one.\[4x=-7\]Divide by four.\[x=-\frac {7}{4}\]
The solutions are 5/4 and -7/4.
