Question

решите уравнение :
0,6z-2/9z=-3.4

Answer 1

0,6Z - 2 = 9Z * ( - 3,4 ) 
0,6Z - 2 = - 30,6Z 
0,6Z + 30,6Z = - 2 
31,2Z = - 2 
Z = ( - 2/1 ) : 156/5 = ( - 10/156) = ( - 5/78) 

Answer 2

0,6Z - 2 = 9Z * ( - 3,4 ) 0,6Z - 2 = - 30,6Z 0,6Z + 30,6Z = - 2 31,2Z = - 2
Z = ( - 2/1 ) : 156/5 = ( - 10/156) = ( - 5/78)
Удачи:)
