So in this question, it is given that pqrs is a parallelogram and the diagnose meet at point t and also pt equal to y, t r equal to 3x plus 1, qt equal to 3x plus 1 and t s and we have to find x and y.
00:15
So we know that in a parallelogram the diagnose biset each other, okay.
00:19
So if the diagnose bice at each other, we can set qt is equal to t s and pt is equal to tr or rt, okay.
00:27
So we'll just equate the things.
00:28
So pt is y and tr is 3x plus 1.
00:30
So y will be equal to 3x plus 1.
00:32
Similarly, qt will be equal to ts, that is 3 y is equal to 4 %10.
00:37
Now we have to just solve for these two equations.
00:39
Now let us for simplification, just multiply this equation 1 into 3.
00:42
So equation 1 into 3.
00:46
Then we get 3 y, 3 .2 is 3y, will be equal to 3 whole into 3x plus 1.
00:53
That is 3y is equal to 9x plus 3.
00:58
So this is our third equation.
01:00
Now see, this is the second equation and this is the 3x plus 3.
01:03
Both are containing 3y...
