Question

Rezolvați ecuațiile:5x=x - 8
x:(-2)=12
2x= -8
3x= -6
x + 8=2

Answer 1

1)5x-x=-8 => 4x= -8 => x=-8/4 => x= -2
2) x= 12*(-2) => x= -24
3) x= -8/2 => x -4
4) x=-6/3 => x= -2
5) x= 2-8 => x= -6

Answer 2

5x-x=-8  ... 4x=-8  ... x= -2 ;
x = 12 * (-2) =-24 ;
x = -8:2 = -4 ;
x = -6:3 = -2 ;
x = 2-8 = -6 ;
