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

Apr 26, 2018

Parallel lines (equal slope). (No solution)

#### Explanation:

$- 2 x + 6 y = 19 \left(1\right) \mathmr{and} 10 x - 30 y = - 15 \left(2\right)$ Multiplying

equation (1) by $\left(- 5\right)$ we get $10 x - 30 y = 95$ . Slope of

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

Therefore "No solution" # [Ans]
