Answer:
Option 1.
Step-by-step explanation:
Consider the given equation is
[tex]7x=7y[/tex]
where x is number.
Using division property of equality, divide both sides by 7.
[tex]\frac{7x}{7}=\frac{7y}{7}[/tex]
Cancel out common factors.
[tex]x=y[/tex]
If x is a number such that 7x = 7y, then we reached on the conclusion that x=y.
Therefore, the correct option is 1.
