4x - 3y = 10
2x - 3y = 2
Subtract the second statement from the first:
2x = 8
highlight%28x+=+4%29
Substitute for x back into either statment (I choose the first):
4(4) - 3y = 10
16 - 3y = 10
-3y = -6
highlight%28y+=+2%29
Prove: (substitute back into both equations:
4(4) - (3)(2) = 10
16 - 6 = 10
10 = 10. OK
2(4) - 3(2) = 2
8 - 6 = 2. OK.
