100

         7                b

   ________ = _______

         9              b-10

         



b = -35

100

26+m > 5(-6+3m)

m<4

100

5(2 - x) - 3(4 - 2x) = 20

x = 22

Use substitution to determine if -1 

is a solution of 

−3(1 + 6r) = 14 − r

True statement.  -1 is a solution.

200

         9                 6

   ________ = _______

         k-7              k

k = -14

200

28 - k > 7( k - 4)

k < 7

200

−11 + 10( p + 10) = 4 − 5(2p + 11)

p = - 7

200

Use substitution to determine if

 2 is a solution of 

3(4 - y) = 2(y + 5)

False statement.  2 is not a solution.

300

         x-3              9

   ________ = _______

         x                10

What is x= 30

300

28 - 7x < -4 (-7x-7)

x > 0

300

10(x + 3) − (−9x − 4) = x − 5 + 3

x = - 2

300

Use substitution to determine if 

1 is a solution of 

−16 + 5n = −7(−6 + 8n) + 3.

True statement.  1 is a solution.
