Let us assume the unknown number to be = x Then we can easily write the equation as 2x - 6 = -36 Dividing both sides of the equation by 2 we get x - 3 = - 18 x = - 18 + 3 x = - 15 So the unknown number that we get is -15.
I hope the procedure is clear
enough for you to understand. You can always use this procedure for
solving similar question in future without taking any outside help.
