Answer:
[tex]w=\frac{3}{2} ,-1[/tex]
Step-by-step explanation:
[tex]3|4w-1|-5=10\\\\3|4w-1|=10+5\\\\3|4w-1|=15\\\\|4w-1|=5\\\\[/tex]
here we have two cases
the number that give an absolute value of 5 are 5 and -5
so we have
[tex]4w-1=5\\\\4w=5+1\\\\4w=6\\\\w=\frac{3}{2}[/tex]
and the other case
[tex]4w-1=-5\\\\4w=-5+1\\\\4w=-4\\\\w=-1[/tex]
