Answer:
[tex]x=-33[/tex]
Step-by-step explanation:
we know that
The formula of midpoint between two points is equal to
[tex]M=\frac{1}{2}(x1+x2)[/tex]
In this problem we have
[tex]M=-3[/tex]
[tex]x1=x[/tex]
[tex]x2=27[/tex]
substitute the values and solve for x
[tex]-3=\frac{1}{2}(x+27)[/tex]
[tex]-6=(x+27)[/tex]
[tex]x=-6-27=-33[/tex]
