1. 3x + 5/6=8/92. ( 4x + 2)/3-(2x+1)/2=(6x+3)/43. 3m/4=m/5-24. n/2=n/7-105. 3(n+4)/4-2/3(3/4-n)=1/2t.... Question from @rismayani14

Mausuf 1. 3x + $\frac{5}{6}$ = $\frac{8}{9}$
kalikan kedua ruas dengan 18, sehingga didapatkan :
54x + 15 = 16
54x = 16 - 15
54x = 1
x = $\frac{1}{54}$

2. $\frac{4x+2}{3}-\frac{2x+1}{2}=\frac{6x+3}{4}$
Kalikan kedua ruas dengan 12, sehingga menjadi :
$4(4x+2)-6(2x+1)=3(6x+3)$
$16x+8-12x-6=18x+9$
$16x-12x-18x=9-8+6$
$-12x=7$
$x=- \frac{12}{7}$

3. $\frac{3m}{4}= \frac{m}{5}-2$
Kalikan kedua ruas dengan 20, menjadi:
$5(3m)=4(m)-20(2)$
$15m=4m-40$
$15m-4m=-40$
$11m=-40$
$m=- \frac{40}{11}$

4. $\frac{n}{2} = \frac{n}{7} -10$
Kalikan kedua ruas dengan 14, menjadi:
$7n=2n-140$
$7n-2n=-140$
$5n=-140$
$n=- \frac{140}{5}=-28$

5. $\frac{3(n+4)}{4}- \frac{2}{3}(\frac{3}{4}-n)=\frac{1}{2}$
Kalikan kedua ruas dengan 12, menjadi:
$3(3(n+4))-4(2( \frac{3}{4} -n))=6$
$9(n+4)-8(\frac{3}{4}-n)=6$
$9n+36-6+8n=6$
$17n+30=6$
$17n=6-30$
$17n=-24$
$n=- \frac{24}{17}$

rismayani14 kak, klo jwban itu bisa dimasukan ke grasik himpunan penyelesaian? soalnya disuruh menggambarnya jg

hsarif13 bisa bikin gambar grafik himpunan penyelesaian?pls

AprilyEkaAsri 1. 3x + 5/6=8/92.
3x =8/9 - 5/6
3x = 16/18 - 15/18
3x = 1/18
x = 3/18 = 1/6
2.( 4x + 2)/3-(2x+1)/2=(6x+3)/4
( 4x + 2)/3 - (2x+1)/2 = (18x + 9)/12
(16x + 8 - 12x + 6)/12 =(18x + 9)/12
(4x + 14)/12 = (18x + 9)/12
(4x + 14) x 12 = (18x + 9) x 12
48x + 168 = 216x + 108 (dikali silang)
168 - 108 = 216x - 48x
60 = 168x
x = 60/168
x = 15/42 = 5/14
3. 3m/4=m/5-2
  3m/4 - m/5 = -2
15m/20 - 4m/20 = -2
11m/20 = -2 (dikali silang)
11m = -40
m = -40/11
4. n/2=n/7-10
  n/2 - n/7=-10
7n/14 - 2n/14 = -10
5n/14 = -10 (dikali silang)
5n = -140
n = - 140/5 = 28
5. 3(n+4)/4-2/3(3/4-n)=1/2
(3n + 12)/4 - (1/2 - 2/3n) = 1/2
  (3n + 12)/4 - (2 - 8/3n)/4 = 1/2
(n/3 +10)/4 = 1/2 (dikali silang)
  (n/3 +10) x 2 = 4
2n/3 + 20 = 4
2n/3 = 4-20
2n/3 = -16 (kali silang)
2n = - 48
n = -28
