Answer:

-45 < x < 5 (see graph below)

Step-by-step explanation:

to isolate x by itself, subtract 20 from all three terms of the equation:

[tex](-25-20)<x+(20-20)<(25-20)[/tex]

once you finish subtracting 20, x should be by itself, making the equation graphable:

[tex]-45 < x < 5[/tex]

since x is not equal to -45 or 25, the graph line endings have open circles.
