Answer:
x > -9 OR x < -26 
Explanation:
there are two possible solutions.
solve absolute value: |0.2x+3.5| > 1.7
now its either 0.2x + 3.5 > 1.7 or 0.2x + 3.5 < -1.7
solution 1 : x > -9
0.2x + 3.5 > 1.7 
subtract 3.5 from both sides, so you get 
0.2x > -1.8 
and then divide both sides by 0.2 or just .2 (theyre both the same thing) 
and you end up with x > -9 
solution 2 : x < -26
0.2x + 3.5 < -1.7
subtract 3.5 from both sides, get 0.2x < -5.2 
divide both sides by 0.2 or .2 
end up with x < -26
hope it helps and i did it right
