Question

The integers X and Y fulfil the condition 2X=5Y. Which can be considered for X+Y?

Answer 1

Answer:

X + Y could equal to $1 \frac{2}{5}X$ or $3 \frac{1}{2}Y$.

Step-by-step explanation:

2X = 5Y

Y = $\frac{2}{5}X$

X = $\frac{5}{2}Y$

Hence, X + Y could equal to X + $\frac{2}{5}X$ = $1 \frac{2}{5}X$ or Y + $\frac{5}{2}Y$ = $3 \frac{1}{2}Y$.

Hence, X + Y could equal to $1 \frac{2}{5}X$ or $3 \frac{1}{2}Y$.
