To solve the equation (4x + 11) - (x + 34) = 67, we need to simplify the expression on both sides of the equation and then solve for x.

First, let's simplify the expression on the left side of the equation:

(4x + 11) - (x + 34) = 67

Remove the parentheses:

4x + 11 - x - 34 = 67

Combine like terms:

(4x - x) + (11 - 34) = 67

3x - 23 = 67

Next, let's isolate the variable x by moving the constant term to the other side of the equation:

3x - 23 + 23 = 67 + 23

3x = 90

Finally, divide both sides of the equation by 3 to solve for x:

3x/3 = 90/3

x = 30

Therefore, the solution to the equation (4x + 11) - (x + 34) = 67 is x = 30.
