as
or
First solve the case
.
(Subtract 1.5 from each side)
(Additive inerse property:
)
(Additive identity property:
)
(Subtract:
)
(Multiply with opositive sign and flip the symbol) \ \
Next solve the casev . 
(Subtract 7 from each side)
(Additive inerse property:
)
(Additive identity property:
)
(Subtract:
)
(Multiply with opositive sign and flip the symbol)

To graph the solutions set, first draw a number line.
\Draw a heavy line between-1.5 and 4.5
\Since -1.5 and 4.5 are not included in the solution set, draw a solid at -1.5 and 4.5.
