12-4x-x=2 what is the Answers to this

x=2

Step-by-step explanation:

12-4x-x=2

Combine like terms

12 -5x =2

Subtract 12 from each side

12-5x-12 =2-12

-5x = -10

Divide each side by -5

-5x/-5 = -10/-5

x =2

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)
