3. (2x+5)+(3x-2) X 2= 46 10x + 6 = 46 10x = 46 - 6 10x = 40 x = 4 P = 2x+5 = 2(4) + 5 = 13 L = 3(4)-2 = 12 -2 = 10
4. lupa gue :v

Nomor 3 : P = 2x+ 5 L = 3x-2 K= 46 dit P dan L berurutan = 2p + 2l = 46 2(2x+5) + 2( 3x-2) = 46 4x + 10 + 6x - 4 = 46 10x = 46-6 10x =40 x = 4 jadi P = 2x + 5 2(4) + 5 = 13 L = 3x-2 3 ( 4) -2 = 12-2 = 10 Jawab : A
No 4 gemar ke 2 = x gemar MTK = 20-x gemar olahraga = 24-x tidak gemar ke 2 = 5 jumlah siswa = 38 dit = yang gemar ke 2 38 = 20-x +x+24-x+5 38= 49 -x 38-49 = -x -11 = -x 11=x
10x + 6 = 46
10x = 46 - 6
10x = 40
x = 4
P = 2x+5 = 2(4) + 5 = 13
L = 3(4)-2 = 12 -2 = 10
4. lupa gue :v
P = 2x+ 5
L = 3x-2
K= 46
dit P dan L berurutan = 2p + 2l = 46
2(2x+5) + 2( 3x-2) = 46
4x + 10 + 6x - 4 = 46
10x = 46-6
10x =40
x = 4
jadi P = 2x + 5
2(4) + 5 = 13
L = 3x-2
3 ( 4) -2 = 12-2 = 10
Jawab : A
No 4
gemar ke 2 = x
gemar MTK = 20-x
gemar olahraga = 24-x
tidak gemar ke 2 = 5
jumlah siswa = 38
dit = yang gemar ke 2
38 = 20-x +x+24-x+5
38= 49 -x
38-49 = -x
-11 = -x
11=x
