3x+7=3(x-2) Distribute the 3
3x+7=3x-6 Add 6 to both sides
3x+7+6=3x Add the 7 and 6
3x+13=3x Subtract 3x both sides
13=?

I would say no solution but it could also be infinitely many solutions

Jonah was standing at an elevation somewhere between-1 1/2
erma4kov [3.2K]

Answer:

=-\frac{23}{12},\ -2 and many others

Step-by-step explanation:

The limits given for Jonah's elevation with regards to sea level are

-1\frac{1}{2} and -2\frac{1}{3}

Any number belonging to that interval could be the requested answer. We'll pick the exact center (mean value) between them:

-1\frac{1}{2} =-\frac{3}{2}

-2\frac{1}{3}=-\frac{7}{3}

Computing the mean value:

\frac{1}{2}\left (-\frac{3}{2}-\frac{7}{3} \right)

=\frac{1}{2}\left (-\frac{23}{6}\right)

=-\frac{23}{12}

Since -2\frac{1}{3}=-2.33

And -1\frac{1}{2}=-1.5

Other numbers like -1.6,-2,-2,3 can be examples of the required answer
