Rewrite the equation with an isolated x.

6y − 3x = 12

x = 2y-4

Step-by-step explanation:

6y − 3x = 12

Subtract 6y from each side

6y − 3x-6y = -6y+12

-3x = -6y +12

Divide each side by -3

-3x/-3 = -6y/-3 + 12/-3

x = 2y-4

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)

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
