Question

na equação 5x + 1/4 = 10x + 6/9 x é igual a?

Answer 1

Oie, Td Bom?!

5x + 1/4 = 10x + 6/9 x

5x + 1/4 = 10x + [6 ÷ 3]/[9 ÷ 3] x

5x + 1/4 = 10x + 2/3 x

12(5x + 1/4) = 12(10x + 2/3 x)

12 . 5x + 12 . 1/4 = 12 . 10x + 12 . 2/3 x

60x + 3 = 120x + 4 . 2x

60x + 3 = 120x + 8x

60x + 3 = 128x

60x - 128x = - 3

- 68x = - 3

x = -3/-68

x = 3/68
