Question

[7/8x+5/6/]-[1/2x+5=0

Answer 1

[ 7/8x + 5/6x ] - [ 1/2x + 5 ] = 0

7/8x + 5/6x -1/2x -5 =0

7/8x + 5/6x -1/2x = 5

x ( 7/8 + 5/6 - 1/2 ) =5

x . 29/24 = 5

x = 5 : 29/24 = 120/29

Answer 2

xin lỗi nhé, làm lại

[ 7/8x + 5/6] -[1/2x + 5] = 0

7/8x + 5/6-1/2x-5=0

7/8x - 1/2x +  5/6 - 5 =0

7/8x-1/2x = 0 + 5 - 5/6 = 25/6

x( 7/8 -1/2) = 25/6

x. 3/8 = 25/6

x = 25/6 :3/8 = 100/9
