-8 - 11 ( 3x + 7 ) < -40x -
9
First distribute the -11
By
distributing, you should get
-8 - 33x -77
< -40x -9 now combine the like terms ( - 8 with -77
)
By combining the like terms, you should
get
-85 - 33x < -40x - 9
add -85 on both sides
By adding, you should
get
-33x < -40x + 76
now add 40x on both sides
by adding, your
should get
7x < 76
divide both sides by 7
By dividing, you
should get
x < 76/7
your answer is
(76/7, -inf.)
