Which equation can be used to solve for $x$ ?
$7 x+28=67$
$7 x+18=67$
$30 x+5=67$
$30 x-5=67$
Solve for $x$.
\[
x=\square
\]
Solution
Solution Steps
Step 1: Identify the relationship between the angles
The diagram shows three angles that form a straight line at point A. The sum of angles on a straight line is 180 degrees.
Step 2: Set up the equation
The given angles are 23°, 67°, and (7x - 5)°. Therefore, the equation is:
\[ 23 + 67 + (7x - 5) = 180 \]
