Ikiwa 5t = 30;
tafuta t.
Solution
5t = 30
5t = 30 [gawanya kwa 5 kila upande]
5 5
t = 6
Hivyo t
= 6

Namba zilizo ndani ya viduara ndio tunatumia kutafuta KKS.
KKS = 2 x 2 x 2
= 8
Hivyo KKS ni 8
ZAMU YAKO......
Tafuta KKS cha 42 na 63.
ALJEBRA A20
Rahisisha a + 3a + 6a + 11a
Solution
= a + 3a + 6a + 11a
= (a + 3a) + (6a + 11a)
= 4a + 17a
= 18a
Hivyo
a + 3a + 6a + 11a = 18a
ZAMU YAKO………
Rahisisha
w + 5w + 7w + 15w.
ALJEBRA A19
Rahisisha
10p + 5m + 2m + p
Suluhu
=10p
+ 5m + 2m + p
=10p
+ p + 5m + 2m
=
11p + 7m
Hivyo 10p
+ 5m + 2m + p = 11p + 7m
ZAMU
YAKO………
Rahisisha
13p + 7m + 2m + 7p

Hivyo KKS ni 8
ZAMU YAKO......
Tafuta KKS cha 18 na 48.
ALJEBRA A18
Rahisisha
4(m + n + p)
Suluhu
=
4(m + n + p) [fungua mabano]
=
(4 x m) + (4 x n) + (4 x p)
=
4m + 4n + 4p
ZAMU YAKO………
Rahisisha
12(a + b + c)
MAGAZIJUTO A2
Kokotoa 2 x 6 + (17 - 3) ÷ 2.
Suluhu
Tunatumia MAGAZIJUTO.
= 2 x 6 + (17 - 5) ÷ 2
= 2 x 6 + 12 ÷ 2 [baada ya kutoa ndani ya mabano]
= 2 x 6 + 6 [baada ya kugawanya]
= 12 + 6 [baada ya kuzidisha]
= 18 [baada ya kujumlisha]
ZAMU YAKO…..
Kokotoa 4 x 9 + (68 + 2) ÷ 5
UWIANO A5
Ikiwa
3: 8 = 10:B; Tafuta B.
Suluhu
3 = 10 [cross multiply]
8 B
3
x B =
10 x
8
3B
= 80
3B = 80 [Gawanya kwa3 kila upande]
3 3
B
= 262/3
Hivyo
B = 262/3
ZAMU YAKO………
Ikiwa
3: 7 = 12 :H; Tafuta H.
ALJEBRA A17
Rahisisha 4(3a + 9e)
Suluhu
= 4(3a + 9e) [fungua mabano]
= (4 x 3a) + (4 x 9e)
= 12a + 36e
ZAMU YAKO…..
Rahisisha
8(4m + 11n)
MAGAZIJUTO A1
Kokotoa 3 x 8 + (20 - 6) ÷ 2.
Suluhu
Tunatumia MAGAZIJUTO.
= 3 x 8 + (20 - 6) ÷ 2
= 3 x 8 + 14 ÷ 2 [baada ya kutoa ndani ya mabano]
= 3 x 8 + 7 [baada ya kugawanya]
= 24 + 7 [baada ya kuzidisha]
= 31 [baada ya kujumlisha]
ZAMU YAKO…..
Kokotoa 3 x 11 + (40 - 8) ÷ 4
Suluhu
Tunatumia MAGAZIJUTO.
= 3 x 8 + (20 - 6) ÷ 2
= 3 x 8 + 14 ÷ 2 [baada ya kutoa ndani ya mabano]
= 3 x 8 + 7 [baada ya kugawanya]
= 24 + 7 [baada ya kuzidisha]
= 31 [baada ya kujumlisha]
ZAMU YAKO…..
Kokotoa 3 x 11 + (40 - 8) ÷ 4
