Required Solution: #color(blue)(x>114#

Using Interval Notation: #color(blue)((114, oo)#

Explanation:

Given:

#color(red)((x/6) + 8 > 27#

Next, we will simplify the inequality and then draw the graph again.

Then, compare the solutions on the graphs for comprehension.

Subtract #color(blue)8# from both sides.

#rArr (x/6) + 8 -color(blue)(8) > 27 - color(blue)(8) #

#rArr (x/6) + cancel 8 - cancel color(blue)(8) > 27 - color(blue)(8) #

#rArr (x/6) > 19#

Multiply both sides by 6

#(x/6)*6 > 19*6#

#(x/cancel 6)* cancel 6 > 19*6#

Simplify to get:

#x> 114#

When we compare the two graphs, we observe that they produce identical solutions.

Hence, our final solutions are:

Solution: #color(blue)(x>114#

Using Interval Notation: #color(blue)((114, oo)#
