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.

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

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
