Answer 2

Exercitiul 3 :

• 2x= -8 => x=-8/2 => x= - 4
• 3x= - 6 => x= -6/3 => x= - 2
• 4x= -8 => x= -8/4 => x= - 2
• 3x= - 9 => x= -9/3 => x= - 3
• -4x= - 12 => x= (- 12) : (- 4) = 3 => x=3
• - 3x= - 15 => x= (- 15) : (-3) => x=5
• -2x = - 14 => x=(-14) : (-2) => x=7
• -4x= - 24 => x=(-24) : (-4) => x=6
