Given: #-0.1<=3.4x-1.8<6.7#

Add 1.8 to everything:

#1.7<=3.4x < 8.5#

Divide everything by 3.4:

#1.7/3.4<= x < 8.5/3.4#

Simplify the fractions:

#1/2 <= x < 5/2#

Graphing instructions:

Put a point on the x axis at #1/2#
Put a very small circle (to indicate that it is not included) on the x axis at #5/2#
Draw a line segment between the point and the small circle.
