Next is to subtract 2 from both-side of the equation
-3x + 2 - 2 = -10 - 2
-3x = -12
Then divide both-side of the equation by -3 to get the value of x
=
(On the left-hand side of the equation -3 at the numerator will cancel out -3 at the denominator while on the right-hand side of the equation -12 will be divided by -3)
