Răspuns :
(x:2-3) *4=7
(x:2-3)=7:4
x:2-3=1.75
x:2=1.75+3
x:2=4.75
x=4.75*2
x=9.5
nu are cum sa fie 2.375 pt ca
(2.375:2-3)*4=7?
(1,1875-3)*4=7?
-1,8125*4=7?
-7.25=7? nu

Este o ecuatie si trebuie rezolvata, trebuie ca tu sa ii afli solutia:
([tex] \frac{x}{2} [/tex]-3) *4=7
[tex] \frac{x}{2} [/tex]*4-3*4=7
2x-12=7
2x=29
x - [tex] \frac{19}{2} [/tex]
=> x=9,5
([tex] \frac{x}{2} [/tex]-3) *4=7
[tex] \frac{x}{2} [/tex]*4-3*4=7
2x-12=7
2x=29
x - [tex] \frac{19}{2} [/tex]
=> x=9,5
