Question

Jika x adalah bilagan asli , tentukanlah himpunan penyelesaian dari persamaan linear berikut
a. 6x + 5=26 - x
b. 2 - 4x = 3
c. x - 12 = 2x + 36
d. -5x - 4x + 10 = 1
e. 2 + x/4 = 5

Answer 1

A. 6x + x + 5 - 26 = 0
7x - 21 = 0
7x = 21
x = 3
b. 2 - 4x = 3
-4x = 3 - 2
x = 1/-4
c. x - 12 = 2x + 36
x - 2x = 36 + 12
-x = 48
x = -48
d. -5x - 4x + 10 = 1
-9x = 1 - 10
x = 1
e. 2 + x/4 = 5
8 + x = 20
x = 20 - 8
x = 12
