Question

Rezolva ecuatia:
5(x-2)-4(x-1)= -7(x+2)

Answer 1

<=>5x-10-4x+4=-7x-14
      x-6=-7x-14 trecem termenii cu x in stanga <=> x+7x=-14+6 
                                                                                  8x=-8 => x=-1

Answer 2

5x-10-4x+4 = -7x -14
x-6 =-7x-14
x+7x =-14+6
8x = -8
x= 8 supra -8 
x = -1
