Question

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

Answer 1

Zero! No solution

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.
