Use a simple substitution: t - u = 2 so t = 2 + u and t + u = 14 so 2 + u + u = 14 2u = 12 and u = 6 and t = 8 and the number is 86

No...what you have to do is take the ln of both sides, then the (-.15t) that is now an exponent becomes a coefficient on the left side like so: lne^(-.15t) = ln(.14) (-.15t)lne = ln(.14) since lne = 1 this becomes now -.15t = ln(.14) …
