What is the solution of the system? use the substitution method. {y+7=3x6x−2y=12 (14, 12) (12, 14) there is no solution. there are an infinite number of solutions.

Given

y + 7 = 3x . . . (1)
6x − 2y = 12 . . . (2)

From equation (1), y = 3x - 7 . . . (3)

Putting equation (3) into equation (2) gives:

6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12 (which is not possible)

Therefore, the given system has no solution.
