How many solutions does this equation have
Y=5x+12
Y=5x+18

Zero!  No solution

Step-by-step explanation:

You have two parallel lines here,  they never intersect.  No solution.

Also if you try solving it, you get a false statement.

y = 5x + 12  = 5x + 18

Solve for x

12 = 18  false.  No solution.

(3x-8) or (3x+8)
