persamaan linear satu variabel tentukan lah variabel a.4p-8=12 b.2a+3=-5 c.2 (3×-1)=2 (2×+3) d.3a-2=-a+18 e.12+3a=5+2a

a.
4p -8 = 12
4p = 12+8
4p = 20
p = 20/4
p = 5

b.
2a +3 = -5
2a = -5-3
2a = -8
a = -8/2
a = -4

c.
2(3x -1) = 2(2x +3)
6x -2 = 4x +6
6x -4x = 6+2
2x = 8
x = 8/2
x = 4

d.
3a -2 = -a+18
3a + a = 18+2
4a = 20
a = 20/4
a = 5

e.
12+3a = 5+ 2a
3a -2a = 5-12
a = -7

semoga membantu
