Let's do this question in the figure of ABCDs Rectangle, it's diagonals meet at G if it is equal to
five X plus one and DG is equal to four X plus 19 Windex.
All right.
Pause the video, give it a try and then let's do it together.
All right.
We know that in a rectangle the diagonals are equal and they bisect each other.
Right.
Because of this is equal to GB's is equal to is equal to these four sides are equal.
Right.
All right.
Now, therefore, it is equal to d.g and we are given igy and.
Right.
It is given us five X plus one and is given us four X plus 19.
So these two are equal and you can just solve for X five X minus four X that gives X over here, 19,
minus one gives eighteen.
So X is equal to 18.
