Answer:
X + Y could equal to [tex]1 \frac{2}{5}X[/tex] or [tex]3 \frac{1}{2}Y[/tex].
Step-by-step explanation:
2X = 5Y
Y = [tex]\frac{2}{5}X[/tex]
X = [tex]\frac{5}{2}Y[/tex]
Hence, X + Y could equal to X + [tex]\frac{2}{5}X[/tex] = [tex]1 \frac{2}{5}X[/tex] or Y + [tex]\frac{5}{2}Y[/tex] = [tex]3 \frac{1}{2}Y[/tex].
Hence, X + Y could equal to [tex]1 \frac{2}{5}X[/tex] or [tex]3 \frac{1}{2}Y[/tex].
