The absolute value of X + 2 = 3 11 of x-9-2 of X + 2 = (x-1) - 2 of X-2 to solve the equation And 113x - 1 / 12 = 105x plus 1 / 6 4x-3 (20-x) = 6x-7 (9-x)

The absolute value of X + 2 = 3 11 of x-9-2 of X + 2 = (x-1) - 2 of X-2 to solve the equation And 113x - 1 / 12 = 105x plus 1 / 6 4x-3 (20-x) = 6x-7 (9-x)

1. X + 2 = 3 x = ± 1
2. It is estimated that this formula is like this
(x-9)/11-(x+2)/2=x-1-(x-2)/2 x=2
3、113x-1/12=105x+1/6 x=1/32
4、4x-3(20-x)=6x-7(9-x) x=1/2
