7 b
________ = _______
9 b-10
b = -35
26+m > 5(-6+3m)
m<4
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.
9 6
________ = _______
k-7 k
k = -14
28 - k > 7( k - 4)
k < 7
−11 + 10( p + 10) = 4 − 5(2p + 11)
p = - 7
Use substitution to determine if
2 is a solution of
3(4 - y) = 2(y + 5)
False statement. 2 is not a solution.
x-3 9
________ = _______
x 10
What is x= 30
28 - 7x < -4 (-7x-7)
x > 0
10(x + 3) − (−9x − 4) = x − 5 + 3
x = - 2
Use substitution to determine if
1 is a solution of
−16 + 5n = −7(−6 + 8n) + 3.
True statement. 1 is a solution.
