[00:00:00]Welcome everyone. So, you guys everyone thought that the answer for this one was supposed to be three, and which is actually correct. 9 * 3 gets you 27, correct? But unfortunately, instead of three, we are we have a bracket, which is saying x + 4.

[00:00:16]So, basically, I can say value of x + 4 is nothing but just three.

[00:00:22]Okay. In order to find the value of x, we will subtract both sides by four.

[00:00:27]So, here you are just left with x + 0, which is just x.

[00:00:30]3 - 4, when you do subtraction, is one.

[00:00:34]But the sign will be of the bigger number, and four over here is negative.

[00:00:37]So, the answer for x is basically minus one.

[00:00:41]Let's put it back over here. So, basically, now you are having nine of nine multiplied by minus one plus four in a bracket.

[00:00:50]So, when you take one from four, the answer is three, and the sign will be of a bigger value, bigger number, which is positive. So, your also answer will be just positive three. Which gets you 27, which is actually your RHS.

[00:01:04]So, here we can say the value of x equals to minus one is absolutely correct for this particular question.

[00:01:10]That's it for today. I will see you in the next video.
