Answer 2

Solving the Equation

To find the common factor and simplify the fraction, we can start by factoring the numerator and then simplifying the fraction.

The given expression is: 7x + 7y / 21

Factoring the Numerator

The numerator, 7x + 7y, can be factored as 7(x + y).

Simplifying the Fraction

Now, we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 7.

So, the simplified form of the given expression is: (x + y) / 3.

This is the simplified form of the given expression after factoring and simplifying the fraction.
