In magic squares, certain numbers have to add up to a certain sum, and be the same sum diagonal,across,and vertical. (Sorry if I didn't explain well)

Arrange the numbers 2,4,6,8,10,12,14,16, and 18 so that the sums of all rows, columns, and diagonals are 30.

Arrange the numbers 3,6,9,12,15,18,21,24,27 so that the sums of all rows, columns, and diagonals are 45.

Please also tell me how to show my work.

P.S. I tried google, but it was confusing.

THANKS A LOT IN ADVANCE!
