Question

Решите уравнение:
3 1/2 * (2/3х + 4/7) = 2 1/3
Заранее спасибо

Answer 1

7/2 × (2/3х + 4/7) = 2 1/3
2 1/3х + 2 = 2 1/3
2 1/3х = 2 1/3 - 2
2 1/3х = 1/3
х = 1/3 : 7/3
х = 1/7

Answer 2

3 1/2 * ( 2/3x + 4/7 ) = 2 1/3 
2/3x + 4/7 = ( 2 1/3 ) : ( 3 1/2 ) 
2 1/3 : 3 1/2 = 7/3 : 7/2 = 2/3 
2/3x + 4/7 = 2/3 
2/3x = 2/3 - 4/7 
2/3 - 4/7 = 14/21 - 12/21 = 2/21 
2/3x = 2/21 
x = 2/21 : 2/3 
x = 3/21
х = 1/7
