system+%28x%2By+=+437%2C%0D%0Ax-y=145%29.

Add the first and the second equations. You will get

2x = 437 + 145 = 582.

Hence, x = 582%2F2 = 291.

Now, substitute this value of x into the second equation to find y. You will get

291 - y = 145.

Hence, y = 291 - 145 = 146.

Answer. x = 291, y = 146.
