Giải phương trình x²/8 - y/27 + x/2 - y/2

To simplify the expression, we can combine like terms.

The given expression is:

x²/8 - y/27 + x/2 - y/2

To combine the terms with x, we add the coefficients:

x²/8 + x/2 = (x² + 4x)/8

To combine the terms with y, we add the coefficients:

-y/27 - y/2 = (-2y - 27y)/54 = -29y/54

Therefore, the simplified expression is:

(x² + 4x)/8 - 29y/54
