(3-x)/2+ (5x-1 )/5= (2-x)/5+ x/2 | ∙10 5(3-x) + 2(5x-1) = 5(2-x) + 5x 15 - 5x + 10x - 2 = 10 - 5x + 5x 5x = -3 /:5 x = -3/5
(3-x)/2+ (5x-1 )/5= (2-x)/5+ x/2 | ∙10 15-5x+10x-2=4-2x+5x 5x+2x-5x=4-15+2 2x=9 x=4,5
(3 - x) /2 + (5x - 1)/5 = (2 - x)/5+ x/2 | ∙10 5(3 - x) + 2(5x - 1) = 5(2 - x) + 5x 15 - 5x + 10x - 2 = 10 - 5x + 5x 5x = -3 /:5 x = -3/5
