5x -3y = 23
7x - 4y = 33
This is simultanreous equations. Arbitrarily decide which letter to eliminate. In this case 'y'
To do this multiply the top eq'n by '-4' and the bottom by '3'
Hence
-20x + 12y = -92
21x - 12y = 99
Add the two eq'ns. This will eliminate 'y'
x = 7
Substitute into either eq'n for 'y'
49 - 4y = 33
-4y = - 16
y = 4
Hence (x,y) = ( 7,4)
