<span>Arrange the first row arbitrarily: 1 2 3 4.
Then there is only one option to begin the next row: 3.
The remaining row must be 4 1 2.
This leaves no options for beginning the third row (1 and 3 are in the same column, and 2 and 4 share the diagonal).</span>
False. You can find the solution more quickly by solving the system algebraically.
-4x + 2y = 18
Since y=-3x+4,
-4x + 2(-3x+4) = 18
-4x - 6x + 8 = 18
-10x = 10
x = -1
y = -3x+4 = 7
