Answer:
x=2.75
Step-by-step explanation:
subtract 3.98x from both sides
6.58-8.36x=3.98x-27.33
6.58-3.98x-8.36x=27.33
subtract 6.58 from both sides
-3.98x-8.36x=27.33-6.58
add like terms:
-12.34x=-33.91
divide both sides by -12.34
x=3391/1234
Collecting like terms
6.58+27.33=3.98x+8.36x
33.91=12.34x
33.91/12.34=12.34/12.34
-2x<5-3
-2x<2
x<-1
