**Solution:**
To solve the given system of equations by the substitution method, we will substitute the value of one variable in terms of the other variable into the other equation. Let's solve the given system of equations step by step.
Given equations:
x = 3y - 19 ...(1)
y = 3x - 23 ...(2)
**Step 1:** Solve equation (1) for x in terms of y.
x = 3y - 19
**Step 2:** Substitute the value of x from equation (1) into equation (2).
y = 3x - 23
y = 3(3y - 19) - 23
y = 9y - 57 - 23
y - 9y = -80
-8y = -80
**Step 3:** Solve for y.
-8y = -80
Divide both sides by -8:
y = -80/-8
y = 10
**Step 4:** Substitute the value of y back into equation (1) to find x.
x = 3y - 19
x = 3(10) - 19
x = 30 - 19
x = 11
Therefore, the solution to the given system of equations is x = 11 and y = 10.
