How do i solve for this absolute value equation ? |12x - 5| = 11

Hello, we know that

And we can write that 12x-5=0 <=> 12x =5 <=> x = 5/12

So,

And, we can write.

So the two solutions are 4/3 and -1/2.

Thank you.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
