Answer 2

Answer: 5

-2x = -10

x = -10/-2    (Bringing 2 to the other side to take the reciprocal)

x = 10/2   (negative sign in the numerator and denominator always cancels off)

x = 5   (10 ÷ 2 = 5)

Now to verify, we can give the value of x in the equation and see if Left Hand Side (LHS) is equal to the Right Hand Side (RHS).

-2x = -10

-2(5) = -10

-10 = -10

LHS = RHS

Therefore verified
