Question

Solve the equation | -9 – 7x| = |23 – 7.|. Graph the solutions, if possible.

Answer 1

the initial equation is:

`\mleft|-9-7x\mright|=\mleft|23-7x\mright|`

Now we can add 7x in bout sides of the equation so:

`\begin{gathered} \mleft|-9-7x+7x\mright|=\mleft|23-7x+7x\mright| \\ \mleft|-9\mright|=\mleft|23\mright| \end{gathered}`

So te problem don't have solution.
