Solve: -25 < x + 20 < 25

denis23 [38]

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:

$(-25-20)$

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

$-45 < x < 5$

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