(X-1/4) : (-2) = -1 + 7/8
x/(-2) +1/8 = (-8 + 7)/8
-x/2 = -1/8 -1/8
-x = 2*(-1/4)
x = 1/2
verifico:
(1/2 -1/4)/(-2) = -1+7/8
(2/4-1/4)/(-2) = -1/8
(1/4)/(-2) = -1/8
-1/8 = -1/8 cqd.
2)
3X -1/2 = X (- 1 + 7/9) + 1/2 X
3x-1/2 = -x +7/9x +1/2x
-1/2 = -x +7/9x +1/2x -3x
-1/2 = (-18x +14x +9x -54x)/18
-1 = (-18x+14x+9x-54x)/9
-1*9 = -72x +23x
-9 = -49x
9/49 = x ==> 1/7
reemplazamos: 3(1/7)-1/2 = (1/7)(-1+7/9)+1/2(1/7)
3/7 -1/2 = -1/7 + 1/7 +1/14
(6-7)/14 = (-2+2+1)/14
1/14 = 1/14 cqd.
3)
2X - 1/4 = 3/2 X + 2/3
2x-3/2x = 2/3 +1/4
(4x-3x)/2 = (8 +3)/12
x/2 = 11/12
x = 11/6
verifico:
2(11/6) -1/4 = 3/2(11/6) +2/3
11/3 -1/4 = 33/12 +2/3
(44-3)/12 =(33+ 8)/12
41/12 = 41/12 cqd.
