Tolong Ya Kakak Dijawab Semuanya Dengan Jalannya ^_^
1 sampai 4.
jangan asal-asalan

Answer 1

Nomor 1a 
24m = 12
1/24 x 24m = 1/24 x 12
m = 12/24
m = 1/2

nomor 1b
3z + 11 = -28
3z + 11 - 11 = -28 - 11
3z = -39
z = -39/3
z = -13

nomor 1c
25 -4y = 6y + 15
25 - 4y + 4y = 6y + 4y + 15
25 = 10y + 15
10y = 25-15
10y = 10
y = 10/10
y = 1

no 1d
-4x - 15 = 1 -8x
-4x + 8x - 15 -1 = 1 - 1 -8x + 8x
4x - 16 = 0
4x - 16 + 16 = 0 + 16
4x = 16
x = 16/4
x = 4

n0 1e
6/a + 2 = 4
a(6/a) + 2 = a(4)
6 + 2 = 4a
8 = 4a
a = 8/4
a = 2

no 2a
6x + 5 = 26 -x
6x + x + 5 = 26 -x+x
7x + 5 = 26
7x = 26-5
7x = 21
x = 21/7
x = 3

no 2b
2-4x = 3
2 - 2 - 4x = 3 - 2
-4x = 1
4x = -1
x = --1/4
x = -0,25

nomor 2c
x -12 = 2x + 36
x -x - 12+12 = 2x - x + 36+12
0 = x + 48
0-48 = x
-48 = x

nomor 2d
-5x - 4x + 10 = 1
-9x + 10 = 1
-9x + 10 - 10 = 1 - 10
-9x = -9
9x = 9
x = 9/9
x = 1

nomor 2e
2 + x/4 = 5
x/4 = 5-2
x/4 = 3
4(x/4) = 4(3)
x = 12

Answer 2

Nomor 1.
Persamaan linear.
a.)


b.)


c.)


d.)


e.)


Nomor 2.
a.)

HP = {3}

b.)

HP = { } (Karena 1/4 bukan bilangan asli)

c.)

HP = { } (Karena x bukan bilangan asli)

d.)

HP = {1}

e.)

HP = {12}

Nomor 3.
a.)


b.)


c.)


Nomor 4.

Sehingga,
x+2 = 5+2
x+2 = 7
