Question

x-2=0,625+0,75x cun rezolv

Answer 1

x-2 = 0,625 =0,75 x 
x-2 = 0,625
x-2 = 0,75x
x= 0,625 + 2
x = 2,625
 x-2 = 0,75 x
2,625 - 2 = 0,75x
0,625=0,75x 
x= 0,625 : 0,75 
x= 0,8(3) 
in calcul vei scrie asa : 
2,625-2= 0,625 = 0,625 rezultatele atat am de scris . 

Answer 2

x-2=625/1000+75x/100
x-75x/100=625/1000+2
(100x-75x)/100=(625+2000)/1000
25x/100=2625/1000
25x·1000=2625·100
25000x=262500
x=262500/25000=2625/250=simplif.cu 5=525/50 simplif.cu 5=105/10=
x=10,5
sau
x-2=0,625+0,75x
x-0,75x=0,625+2
0,25x=2,625
x=2,625/0,25=2625/1000:25/100=2625/1000x100/25=2625/10x1/25=simplif.cu 25=105/10
x=105/10=10,5
