Question

2 целых 2/5x + 3 целых 2/15 = 3 целых 2/5x + 2 целых 1/3

Answer 1

2 целых 2/5x + 3 целых 2/15 = 3 целых 2/5x + 2 целых 1/3

2 2/5x - 3 2/5x = 2 1/3 - 3 2/15

-x = 2 5/15 - 3 2/15

-x = -12/15

x = 4/5

Answer 2

$frac{12}{5} x + frac{47}{15} = frac{17}{5} x + frac{7}{3} \ \ 36x + 47 = 51x + 35 \ \ 36x - 51x = 35 - 47 \ \ - 15x = - 12 \ \ x = 0.8$
