Question

Tentukan himpunan penyelesaian dari persamaan linear berikut :
a. 24m = 12
b. 3z+11 = -28
c. 25-4y = 6y+15
d. -4x - 15 = 1 - 8x
e. 6/a+ 2 = 4
TOLONG JAWAB YAH :-)

Answer 1

A. 24 m =12 >> m = 12/24 >> m = 1/2
b. 3z + 11 = -28 >> 3z = -28-11 >> 3z = -39 >> z = 3
c. 25-4y = 6y+15 >> 2y = 10 >> y = 2
d. -4x - 15 = 1 - 8x >> 4x = 16 >> x = 4
e. 6/a + 2 = 4 >> 6/a = 2 >> 2a = 6 >> a = 3
   

Answer 2

A. 24m = 12 | m = 12/24 | m = 1/2
b. 3z+11 = -28 | 3z = -28-11 | 3z = -39 | z = -13
c. 25-4y = 6y+15 | 25-15 = 6y+4y | 10 = 10y | 1 = y atau y=1
d. -4x-15 = 1-8x | -4x+8x = 1+15 | (-4x)=16 | X = -4
e. 6/a + 2 = 4
6/a =4-2
6 = 2a
2a = 6
a= 3
