Final answer:

To solve the system of linear equations by substitution, solve one equation for one variable and substitute it into the other equation. The solution to the given system is x = 4 and y = 3/2.

Step-by-step explanation:

To solve the system of linear equations by substitution, we will solve one equation for one variable and substitute that expression into the other equation. Let's solve the second equation for x:

6y = x + 5

x = 6y - 5

Now substitute this expression for x in the first equation:

-5(6y - 5) + 6y = -11

-30y + 25 + 6y = -11

-24y = -36

y = -36 / -24

y = 3/2

Now substitute this value of y back into either of the original equations to find x:

6(3/2) = x + 5

9 = x + 5

x = 9 - 5

x = 4

Therefore, the solution to the system of equations is x = 4 and y = 3/2.
