Answer:

4

Step-by-step explanation:

To make your equation, you basically write all the steps down with x as your number and then set it equal to 34 (wow, that was very confusing, sorry!). This means that your equation would be (5x-3)2=34. Now, you'll solve this by starting with distributing the 2 (2*5x and 2*-3), which will give you the equation 10x-6=34. Next, add six to both sides (10x-6+6=10x and 34+6=40), so you should get 10x=40. Lastly, divide both sides by 10 (10x/10=x and 40/10=4) to get x=4. I'd also advise checking your answer by multiplying 4 by 5 (20), then subtracting 3 (20-3=17), and multiplying it by 2 (2*17=34). :)
