Question

| x-5 | : 2x = -4
Materi:persamaan nilai mutlak
Tolong dijawab dgn benar dan jelas beserta HPnya.thx

Answer 1

L x - 5 l : 2x = -4
*( x - 5 ) : 2x = -4
x - 5 = -4 x 2x
x - 5 = -8x
x + 8x = 5
9x = 5
x = 5/9
*-( x - 5 ) : 2x = -4
-x + 5 = -4 x 2x
-x + 5 = -8x
-x + 8x = -5
7x = -5
x = -5/7

HP = {5/9, -5/7}
