Question 17

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

(a) 2
(b) 6
(c) -6
(d) -2

Answer 1

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

(a) Put x = 2
$\Rightarrow -6+2=-12\Rightarrow -4=-12\therefore LHS\ne RHS$

(b) Put x = 6
$\Rightarrow -6+6=-12\Rightarrow 0=-12\therefore LHS\ne RHS$

(c) Put x = -6
$\Rightarrow -6+(-6)=-12\Rightarrow -6-6=-12\Rightarrow -12=-12\therefore LHS=RHS\left(saitsfied\right)$

Now, there is no need to check the next option,
Hence, x = -6 satisfies the given equation.
