Answer:

x = 3, y = 11

Step-by-step explanation:

Given

2x + 3xi + 2y = 28 + 9i

Compare coefficients of like terms on both sides.

Comparing i terms

3x = 9 ( divide both sides by 3 )

x = 3

Comparing constant terms

2x + 2y = 28 ← substitute x = 3

2(3) + 2y = 28

6 + 2y = 28 ( subtract 6 from both sides )

2y = 22 ( divide both sides by 2 )

y = 11
