Jika x adalah bilangan asli , terntukanlah 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 Tolong jawab yah beserta cara kerja nya ....
MaulanaRahmana. 6x + 5 = 26 - x 6x + x = 26 - 5 7x = 21 x = 21/7 x = 3
b. 2 - 4x = 3 -4x = 3 - 2 x = 1 / (-4) x = -1/4
c. x - 12 = 2x + 36 x - 2x = 36 + 12 -x = 48 x = -48
d. -5x - 4x + 10 = 1 -9x = 1 - 10 -9x = -9 x = 1
e. 2 + x/4 = 5 x/4 = 5 - 2 x/4 = 3 x = 3 x 4 x = 12
