Answer

Finally, solve the equation, which gives \( 4 = 7 \).

Steps

Step 1 ：First, substitute the given values of \( x \) and \( y \) into the equation, which gives \( 2(2)^2 - 3(3) + 5 = 7 \).

Step 2 ：Then, simplify the equation, which gives \( 2(4) - 9 + 5 = 7 \).

Step 3 ：Further simplification gives \( 8 - 9 + 5 = 7 \).

Step 4 ：Finally, solve the equation, which gives \( 4 = 7 \).
