Let's do this question in the figure of ABCDs Rectangle, it's diagonals meet at G if it is equal to

2
00:00:09,370 --> 00:00:15,340
five X plus one and DG is equal to four X plus 19 Windex.

3
00:00:15,640 --> 00:00:16,030
All right.

4
00:00:16,030 --> 00:00:19,100
Pause the video, give it a try and then let's do it together.

5
00:00:19,540 --> 00:00:20,010
All right.

6
00:00:20,320 --> 00:00:25,060
We know that in a rectangle the diagonals are equal and they bisect each other.

7
00:00:25,210 --> 00:00:25,590
Right.

8
00:00:25,750 --> 00:00:33,040
Because of this is equal to GB's is equal to is equal to these four sides are equal.

9
00:00:33,040 --> 00:00:33,280
Right.

10
00:00:33,790 --> 00:00:34,240
All right.

11
00:00:34,510 --> 00:00:40,150
Now, therefore, it is equal to d.g and we are given igy and.

12
00:00:40,150 --> 00:00:40,470
Right.

13
00:00:40,600 --> 00:00:45,610
It is given us five X plus one and is given us four X plus 19.

14
00:00:45,880 --> 00:00:52,870
So these two are equal and you can just solve for X five X minus four X that gives X over here, 19,

15
00:00:52,870 --> 00:00:54,190
minus one gives eighteen.

16
00:00:54,200 --> 00:00:56,140
So X is equal to 18.
