Answer:
a= 3/11
b = 2/11
Step-by-step explanation:
a(1) + b(4) = 1
a + 4b = 1
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
b = 1-3(3/11)
b= 2/11
12) -5k - 19 = 5 - 13k
-5k = 24 - 13k
8k = 24
k = 3
14) -15n + 16 = 86 - 29n
-15n = 70 - 29n
14n = 70
n = 5
16) 13 - 3p = -5(3 + 2p)
13 - 3p = -15 - 10p
-3p = -28 - 10p
7p = -28
p = -4
18) 14a - 93 = 49 - 57a
14a = 142 - 57a
71a = 142
a = 2
20) 8v = 2(4v + 2)
8v = 8v + 4
No solution
22) 2(-4h - 13) = 37 + 13h
-8h - 26 = 37 + 13h
-8h = 63 + 13h
-21h = 63
h = -3
24) 11n - 3 = 9 + 5n
6n = 12
n = 2
26) -9n - 12 = 8 - 4n
-5n - 12 = 8
-5n = 20
n = -4
