2x - 3y = 4
x + 4y = 3
Write the augmented matrix:
2 -3 4
1 4 3
Multiply the first row by 1/2:
1 -3/2 2
1 4 3
Subtract the second row from the first row:
1 - 3/2 2
0 -11/2 -1
Multiply the second row by -2/11:
1 -3/2 2
0 1 2/11
Multiply the second row by 3/2 and add it to the first row:
1 0 25/11
0 1 2/11
Thus x = 25/11 and y = 2/11
