You can
put this solution on YOUR website!
Instead of doing your problem for you, I'll do one EXACTLY IN EVERY
DETAIL like yours. Then you can use it as a model to solve yours by.
|x-2| - 7 ≤ 3
Add 7 to both sides
|x-2| ≤ 10
±(x-2) ≤ 10
Make two inequalities by using +(x-4) in one and -(x-4) in the other
+(x-2) ≤ 10 -(x-2) ≤ 10
x-2 ≤ 10 -x+2 ≤ 10
x ≤ 12 -x ≤ 8
x ≥ -8 (reversing because we divided by a negative)
x ≤ 12 says we shade left of 12 and x ≥ -8 says we shade right
of -8. So we do both, darkening the endpoints because the inequalities
are ≤ and ≥, rather than < and >.
--------●===========================================================●------
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14
That says we put -8 on the left, then ≤ x to stand for all the shaded
part of the number line and a ≤ 12 on the right
Answer: -8 ≤ x ≤ 12
Now do yours EXACLY the same way.
