Which of the following numbers satisfy the equation –6 + x = –12?

Let us put the values given in the options in equation –6 + x = –12


(a) Put x = 2


⇒ –6 + 2 = –12


⇒ –4 = –12


⇒ LHS ≠ RHS


(b) Put x = 6


⇒ –6 + 6 = –12


⇒ 0 = –12


⇒ LHS ≠ RHS


(c) Put x = –6


⇒ –6 – 6 = –12


⇒ –12 = –12


⇒ LHS = RHS


(d) Put x = –2


⇒ –6 – 2 = –12


⇒ –8 = –12


⇒ LHS ≠ RHS
