Question

Solve:
y = 2x -11
-3y = -6x -15

Answer 1

9514 1404 393

Answer:

no solution (parallel lines)

Explanation:

You observe that the coefficient in the second equation are all multiples of 3. Dividing that equation by -3 gives the two equations ...

• y = 2x - 11
• y = 2x + 5

The slopes are the same (2) and the intercepts are different (-11, 5), so the lines are parallel. There is no solution.
