Question

solve the equation |-6x|=30

Answer 1

You have already isolated the absolute value, so \[\left| -6x \right|=6x\]
Then divide 30/6

\[x =5\]

Answer 2

u have to use this theorem
\[ \large |a|=b\quad\Leftrightarrow\quad a=\pm b \]

Answer 3

so |-6x|=30 becomes
\[ \large -6x=30\quad\text{or}\quad -6x=-30 \]
