Question

решите уравнение для 6 класса 3*(2 1/2х-0.2)-15 1/15=6-(2/3-0.5х)

Answer 1

3*(2 1/2х-0.2)-15 1/15=6-(2/3-0.5х)

3*(2 1/2х-0.2) = 6 3/2X - 0,6 = 7 1/2X - 0,6 = 7,5X - 0,6

6-(2/3-0.5X) = 6 - 2/3 - 0.5X = 5 1/3 - 0.5X

7,5X - 0,6 = 5 1/3 - 0,5X

8X = 5 1/3 + 0,6
 5 1/3 + 6/10 = 5 1/3  + 3/5 = 5 5/15 + 9/15 = 5 14/15

8X = 5 14/15

X = 5 14/15:8 = 89/15:8=89/120
