Answer:

Infinite

Explanation:

The equation has an infinite number of solution because they are the same line when graphed. They "intersect" an infinite number of times because they are always touching.

Their expressions are equal as well:

5x+48+7x = 12(x+4)

Separately simplify:

5x+48+7x (collect like terms)

=12x + 48

12(x+4) (distribute over brackets)

=12x + 48

12x+48 = 12x+48
