Can someone tell me how to solve this 2[ x-2(5+2x) ]=5(x-15)

2[ x-2(5+2x) ]=5(x-15)

2[ x- 10 - 4x] = 5x - 75

2[ -3x - 10] = 5x - 75

-6x - 20 = 5x - 75

11x = 55

x = 5

-
2 [ x - 10 - 4x ] = 5x - 75

2 [ - 3x - 10 ] = 5x - 75

- 6x - 20 = 5x - 75

55 = 11 x

x = 5

You presented the question in a very clear fashion by using brackets in the correct manner.
