Which would be the best first step you could make to solve the equation?
A. Combine ax - 7 to get -7x
B. divide ax by a and 26 by a
C. subtract 7 from the left side of the equation
D. add 7 to both sides of the equation

To solve the equation \( ar - 7 = 26 \) for \( x \), the best first step you could take is:
D. add 7 to both sides of the equation.
This will help isolate the term involving \( x \) on one side of the equation.
So, if you add 7 to both sides, the equation becomes:
\[ ar = 33 \]
From there, you can continue solving for \( x \).
I apologize for the mix-up in my previous response regarding the variable. Let me clarify your original equation \( ar - 7 = 26 \).
From your equation \( ar - 7 = 26 \), adding 7 to both sides indeed is the correct first step: \[ ar - 7 + 7 = 26 + 7 \] This simplifies to: \[ ar = 33 \]
If your intention was to solve for \( r \), at this point, you'd divide both sides by \( a \): \[ r = \frac{33}{a} \]
Thus, the best first step remains D. add 7 to both sides of the equation to move toward isolating the term involving \( r \).
Thank you for your patience, and I hope this clarification helps! If you have any more questions or need further assistance, feel free to ask.
