Question

Hai kakak kakak tolong bantu aku yaa, bsok mau di kumpul nih PR nya. aku kasih 100 poin yg mau jawab semua pertanyaan ku.

Answer 1

9)
6a - 2 = 1

6a = 2+1

6a = 3

a = 3/6

4a = 4 x 3/6

4a = 12/6

4a = 2


10)
-5x + 3y = -19
4x - y = b

-5(a + 1) + 3(a - 4) = -19
-5a -5 + 3a - 12 = -19
-2a - 17 = -19
-2a = 17-19
-2a = -2
a = -2/-2
a = 1

4(a + 1) - ( a - 4) = b
4(1+1) - (1 -4) = b
4(2) - (-3) = b
8 + 3 = b
b = 11

a + b

= 1 + 11

a + b = 12

Answer 2

Mata Pelajaran : MTK

Solusi : Nomor 9.  

6a - 2 = 1                     4a = 4x3

6a = 2+1                      4a = 12 : 6

6a = 3                          4a = 2

a = 3 : 6  = 2

Nomor 10.

-5x + 3y = -19

4x - y = b

-5(a + 1) + 3(a - 4) = -19

-5a -5 + 3a - 12 = -19

-2a - 17 = -19     -2a = 17-19    -2a = -2    a = -2 : -2    a =1

4(a + 1) - ( a - 4) = b  

4(1+1) - (1 -4) = b

4(2) - (-3) = b

8 + 3 = b

b = 11

a + b

= 1 + 11

a + b = 12
