(4x+6):2 = 4x : 2 + 6 : 2 = 2x + 3
(6y - 9 ) : 3 = 6y : 3 - 9 : 3 = 2y - 3
(8x - 5) : (-4) = 8x : (-4) - 5 : (-4) = -2x - (-1,25) = -2x + 1,25
(-2,7 - 0,9y ) : (-3) = -2,7 : (-3) - 0,9y : (-3) = 0,9 - (-0,3y) = 0,9 + 0,3y
(2 1/2z - 1/4y) : 1/4 = 2 1/2z : 1/4 - 1/4y : 1/4 = 3/2z * 4/1 - 1y = 6z - 1y
(x - 4y + 2z) : (-1) = x : (-1) - 4y : (-1) + 2z : (-1) = -1x - (-4y) + (-2z) = -1x + 4y - 2z
25x + 10y = 25x + 10y = 5x + 2y = 5x + 2y

-(20x-8) = -1 * 20x - -1 * 8 = -5x - (-2) = -5x + 2
