Rezolvati ecuatiile: a)8x=16 b)4x-8=0

Răspuns :

Rezolvare  :
a ) 8x = 16 
x = 16:8
x = 2 
b ) 4x - 8 - 0 
4x = 0+8
4x = 8
x = 8:4
x = 2 
a) [tex]8x=16 =\ \textgreater \ x= \frac{16}{8} =\ \textgreater \ x=2[/tex]
b) [tex]4x-8=0 =\ \textgreater \ 4x=8 =\ \textgreater \ x= \frac{8}{4} =\ \textgreater \ x=2 [/tex]
