y – 5x = –6 and 3y – 15x = –12

To solve this system of equations, we can use the method of substitution.

First, let's solve the first equation, y - 5x = -6, for y. Adding 5x to both sides of the equation, we get:

y = 5x - 6

Now, we can substitute this expression for y into the second equation, 3y - 15x = -12:

3(5x - 6) - 15x = -12

Multiplying out the expression, we get:

15x - 18 - 15x = -12

Combining like terms, 15x - 15x = 0, so the equation becomes:

-18 = -12

This is not a true statement, which means there is no solution to this system of equations.
