Answer:
y=-47
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points in a number line is given by
[tex]m=(\frac{x_1+x_2}{2})[/tex]
we have
[tex]x_1=y\\x_2=33\\m=-7[/tex]
substitute the given values
[tex]-7=(\frac{y+33}{2})[/tex]
solve for y
[tex]-14=y+33\\y=-14-33\\y=-47[/tex]
