Given the following expression:
[tex]3|-8x|+8=80[/tex]The symbol | | represents the absolute value.
The absolute value of a number is always positive.
Therefore, the absolute value of -8x is 8x.
We get,
[tex]3|-8x|+8=80[/tex][tex]3(8x)+8=80[/tex][tex]24x+8-8=80\text{ - 8}[/tex][tex]24x\text{ = 72}[/tex][tex]\frac{24x}{24}\text{ = }\frac{\text{72}}{24}[/tex][tex]\text{ x = }3[/tex]Therefore, x = 3.
