Question

решите уравнение
1.5x + 3 1/3 = 2.5

Answer 1

1.5Х = 2.5 - 3 1/3 
==============
2.5 - 3 1/3 = 5/2 - 10/3 = ( 15 - 20) / 6 = ( - 5/6 )
===============
1.5Х = ( - 5/6 )
3/2Х = ( - 5/6) 
9/6Х = ( - 5/6 ) 
9Х = ( - 5 )
Х = ( - 5/9 )

Answer 2

1,5x+3 1/3=2.5 
1.5x=2.5 - 3 1/3
1.5x= 2 1/2 - 3 1/3
1.5x= 5/2 - 10/3 
1.5x= 15/6 - 20/6 
1.5x= -5/6 
x=-5/9
