Question

2/3:(2/3x-2/3)-2/3=2/3 пз помогите.

Answer 1

2/3  /(2/3 *х - 2/3) - 2/3 = 2/3
2/3  / (2/3 х - 2/3 ) = 2/3 +2/3
2/3  /(2/3 х - 2/3) = 4/3
2/3 = 4/3 * (2/3 х - 2/3) , разделим левую и правую часть уравнения на 2/3 , получим : 1 = 2 (2/3 х - 2/3)
1 = 4/3 х - 4/3
4/3х = 1 +4/3
4/3 х = 7/3
х = 7/4 = 1 3/4
