14x/35-5x/35+x/35=10x/35 que si s esimplifica da 2/7(divido entre 5)

(2x/5) - (x/7) + (x/35) = (2/5)x - (1/7)x + (1/35)x

= [(2/5) - (1/7) + (1/35)]x

= [ [(2 * 7) - (1 * 5) + 1] / (5 * 7) ]x

= [(14 - 5 + 1) / 35 ]x

= (10/35)x

= [(2 * 5) / (7 * 5)]x

= (2/7)x

= 2x/7

2x/5 - 4x/35

10x/35

2x/7
