Answer:
x = 3, y = 11
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
