Hello students, in this problem given 8x -2y equal to 6, consider this as equation number 1 and simplifying equation 1 we have 4x -y equal to 3.
00:15
This can be written as y equal to 4x -3.
00:19
Consider this as equation number 2.
00:22
And we have to find the given points in which given points are the solution of this equation.
00:29
So first one is 3, -1.
00:32
So let us take x is equal to 3 and y equal to minus 1.
00:37
Then the equation 2 becomes 4x -3 that is 4 of 4x -3 that is equal to 4 of 3 -3 that is equal to 12 -3.
00:50
This is 9 which is not equal to minus 1.
00:55
Hence this is not a solution.
01:02
And second one is minus 2, -11.
01:07
So then the equation 2 is minus 11 equal to 4 of minus 2 minus 3.
01:14
So minus 11 equal to minus 8 minus 3.
01:16
So here minus 11 is equal to minus 11...
