Start with the given inequality
or
Break up the absolute value
Now let's solve the first inequality
Start with the given inequality
Add 14 to both sides
Subtract 2x from both sides
Combine like terms on the left side
Divide both sides by 3 to isolate x
--------------------------------------------------------------
Answer:
So our answer is
(which is approximately
in decimal form)
Now let's solve the second inequality
Start with the given inequality
Add 14 to both sides
Add 2x to both sides
Combine like terms on the left side
Divide both sides by 7 to isolate x
Divide
--------------------------------------------------------------
Answer:
So our answer is
--------------------------------------------------------------
Answer:
So our two answers are
or
So in interval notation our answer is
(-
,2] U [14/3 ,
So if we graph the solutions, we get
