Question

|8x-3|=|2x-4| resolvam a equacão modular!

Answer 1

8x - 3 = 2x - 4

ou

8x - 3 = -( 2x - 4)
__________

Resolvendo o primeiro:

8x - 3 = 2x -4

8x - 2x = -4 + 3

6x = -1

x = -1/6
__________

Ou

8x - 3 = -( 2x - 4)

8x - 3 = -2x + 4

8x + 2x = 4 + 3

10x = 7

x = 7/10
__________


S = { -1/6, 7/10 }
