Question

Tell whether each equation has one zero or infinitely many solutions.
2. 1/2n + 7 = (n+14)/2

Answer 1

n/2 + 7 is always equal to (n + 14)/2

Explanation:

Both equations are the same, re-written.

Simplify the following:

n/2 + 7

Put each term in n/2 + 7 over the common denominator 2: n/2 + 7 = n/2 + 14/2:

n/2 + 14/2

n/2 + 14/2 = (n + 14)/2:

Answer: (n + 14)/2
