Question

How do you solve `-2x + 6y = 19` and `10x – 30y = -15` using substitution?

Answer 1

Parallel lines (equal slope). (No solution)

Explanation:

`-2 x+6 y=19 (1) and 10 x -30 y= -15 (2)` Multiplying

equation (1) by `(-5)` we get `10 x -30 y= 95` . Slope of

both the lines are equal , so they are parallel lines.

Therefore "No solution" # [Ans]
