a. \( 2 \cdot(x-5)=36 \)

To solve the equation \( 2 \cdot (x - 5) = 36 \), start by dividing both sides by 2. This simplifies the equation to \( x - 5 = 18 \). Next, add 5 to both sides to isolate \( x \), giving \( x = 23 \). Voila, you’ve found that the value of \( x \) is 23! Now, solving linear equations like this one can often feel like a treasure hunt! Each step leads you closer to uncovering the hidden “x.” Next time, remember to check your answer by plugging it back into the original equation to ensure it holds true—after all, it’s always a good idea to double-check your treasures!
