First you need to use the distributive property: 27(x+4)=-6
27x+108=-6
then you need to subtract 108 from -6 to
get x alone. 27x= 102
Lastly divide 102 by 27 to finally get x alone: x=3.777
the answer would be: x= 3.77 or 3.8

Answer:
Step-by-step explanation:
The problem can be modeled by using the compound growth formula.
Given, Initial number P_0 of people who Nicholas sent the chain letter t=50
The growth rate, r =99%=0.99
Period of Growth,k =12 Weeks
Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:
Lets say that Williams current age is x, since it is currently unknown
From here we know that in 15 years (x+15) he will be 3 times his age 5 years prior (3x-5). Thus we can set these equations up as equal to one another
1) x + 15 = 3(x - 5)
2) x + 15 = 3x-15
3) 30= 2x
4) 15 = x
5) Now this age is his current age of 15 years, but they also want his age 15 years from now
The equation is x + 15 = 3(x - 5)
This should be correct now, sorry for the misconception. Good luck
