1/2g-4=2g-1/2g+4
does it have one solution or infinitely many solutions ? Why ?

Explanation:
2g - (1/2)g = (4/2)g - (1/2)g = (3/2)g
The original equation becomes (1/2)g-4 = (3/2)g+4
The slopes are 1/2 and 3/2 respectively. Since the slopes are different, the two lines cannot be parallel.
Since we don't have parallel lines, they intersect at exactly one point leading to exactly one solution.
Answer:
the first one- one solution
the second one- infinitely many solutions
Step-by-step explanation:
One solution as one intersection point
=========
considering this equation as lines, these are two overlapping lines, so there are infinitely many solutions
