To solve the system of equations:

x - 5y = 15 (Equation 1)

4x - 3y = 26 (Equation 2)

There are several methods for solving a system of equations, but we will use the elimination method here. We will eliminate one variable by adding or subtracting the two equations.

Multiplying Equation 1 by 4, we get:

4x - 20y = 60 (Equation 3)

Now we can subtract Equation 2 from Equation 3:

(4x - 20y) - (4x - 3y) = 60 - 26

Simplifying, we get:

-17y = 34

Dividing both sides by -17, we get:

y = -2

Substituting this value of y in Equation 1, we get:

x - 5(-2) = 15

Simplifying, we get:

x + 10 = 15

Subtracting 10 from both sides, we get:

x = 5

Therefore, the solution to the system of equations is:

x = 5 and y = -2

In other words, the two equations intersect at the point (5, -2).
