Question

me ayudan von este problema :. 3(2x+5)÷2-5(x-3)÷8=x+2

Answer 1

3 .(2x + 5) : 2 - 5 .(x - 3) : 8 = x + 2
(6x + 15) : 2 - (5x - 15) : 8 = x + 2 (Aplicamos distributiva)
(6x + 15) : 2 - (5x - 15) : 8 - x = 2
(6x + 15) : 2 - (5x - 15) - x = 2 . 8
(6x + 15) : 2 - (5x - 15) - x = 16
(6x + 15) : 2 - 5x - x = 16 + 15
(6x + 15) : 2 - 5x - x = 31
(6x + 15) - 5x - x = 31 . 2
(6x + 15) - 5x - x = 62
6x - 5x - x = 62 - 15
6x - 5x - x = 47
1x - x = 47
0 x = 47
