tentukan himpunan penyelesaiannya dan gambarlah grafiknya a.6x=18 b.4y-8=y+1 c.7a-6=1 d.14 -3x=-5 e.2/5p-6=0

a) 6x = 18
x = 3

b) 4y - 8 = y + 1
4y - y = 1 + 8
3y = 9
y = 3

c) 7a - 6 = 1
7a = 1 + 6
7a = 7
a = 1

d) 14 - 3x = - 5
- 3x = - 5 - 14
- 3x = - 19
x = 19/3

e) 2/5p - 6 = 0
2/5p = 6
p = 6 ÷ 2/5
p = 6 × 5/2
p = 30/2
p = 15
