Answer: The solution is (1, 2)

Step-by-step explanation:

The given equations are

5x - 4y = - 3

x - 6y = - 11

We would apply the method of substitution. From the second equation, if we add 6y to both sides, it becomes

x - 6y + 6y = 6y - 11

x = 6y - 11

We would substitute x = 6y - 11 into the second equation. It becomes

5(6y - 11) - 4y = - 3

By expanding the parentheses, it becomes

30y - 55 - 4y = - 3

By collecting like terms, we have

30y - 4y = - 3 + 55

26y = 52

Dividing both sides by 26, we have

26y/26 = 52/26

y = 2

Substituting y = 2 into x = 6y - 11, we have

x = 6(2) - 11

x = 12 - 11

x = 1

The solution is (1, 2)
