Question

5×(7x-2)-10x=15+2×(x-5)

Answer 1

5x (7x - 2) - 10x = 15 + 2x (x - 5)
35x - 10x - 10x = 15 + 2x - 10x
25x - 10x = 15 + - 8x
15x = 15 + 8x
15x - 8x = 15
7x = 15
x = 15/7

Espero ter ajudado :)

Answer 2

1º    5x(7x-2)= 35x-10x

2º  -10x=

3º  15+

4º  2x(x-5)= 2x -10x

5º  35x-10x-10x=15+2x-10x

15x=15 - 8x

15x+8x=15

23x=15

x=15/23  ou x= 0,65
