Final answer:

To solve the system of equations using the substitution method, we solve one equation for a variable and substitute that value into the other equation. The solution to the system of equations is x = -7 and y = -2.

Step-by-step explanation:

To solve the system of equations using the substitution method, we can start by solving one equation for a variable and then substituting that value into the other equation. Let's solve the first equation for x:

x + 6y = -19

x = -6y - 19

Now we can substitute this expression for x into the second equation:

-2(-6y - 19) + 5y = 4

Simplify and solve for y:

12y + 38 + 5y = 4

17y = -34

y = -2

Substitute this value of y back into the first equation to find x:

x + 6(-2) = -19

x + (-12) = -19

x = -7

Therefore, the solution to the system of equations is x = -7 and y = -2.
