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. 6/a + 2 = 4

Answer 1

A. 24m=12
= m = 1/2(dibagi 24)
b. 3z +11=-28
= 3z = -28-11
= 3z = -39
= z = -13(dibagi3)
c. 25-4y=6y+15
= 10-4y=6y
= 10 = 10y
= 1 = y
d. -4x-15=1-8x
= -4x-16=-8x
= -16= -4x
= -4 = -x
= 4 = x
e. 6/a +2 = 4
= 6/a = 2
= 6/6a = 2/6 (x1/6)
= a = 1/3
