Question

Tentukanlah himpunan penyelesaian dari persamaan linear berikut
a) 24m = 12
b) 3z + 11 = -28
c) 25 - 4y = 6y + 15
d) - 4x - 15 = 1 - 8x
e) + 2 = 4

Answer 1

24m=12
m = 24/12
m = 2
3z+11= -28
3z = -28-11
3z = -39
z= -39/3
z= -13
25-4y=6y+15
-4y-6y = 15-25
-10 y= -10
y= -10/-10
y=1
-4x-15=1-8x
-4x+8x = 15 +1
4x = 16
x= 16/4
x= 4
maaf kalo salah ya

Answer 2

A. 24m = 12, m = 0,5 b. 3z + 11 = -28, 3z + 11 - 11 = -28 - 11, 3z = -39, z = -13 c. 25 - 4y = 6y + 15, 25 - 25 - 4y = 6y + 15 - 25, -4y = 6y - 10, -4y - 6y = 6y - 6y - 10, -10y = -10, y = 1 d. -4x - 15 = 1 - 8x, -4x - 15 + 15 = 1 + 15 - 8x, -4x = 16 - 8x, -4x + 8x = 16 - 8x + 8x, 4x = 16, x = 4 Yang e. saya kurang tau.. Nanti kalau saya tau, saya beri tau.. Maaf kalau salah.. Semoga membantu..
