Sure, I will help you. The answer you are looking for is x=11.
Solution/Explanation:
Write out the equation:
3(x+5)=5x-7
Using the Distributive Property on the LEFT SIDE,
3x+15=5x-7
Next, subtracting 3x from both sides,
3x-3x+15=5x-3x-7
15=2x-7, or 2x-7=15
2x-7=15
Now, adding seven to both sides,
2x-7+7=15+7
2x=22
Finally, dividing both sides by 2,
So, therefore the final answer is x=11. And, also, the next step would be written as 3x+15=5x-7, as stated above, preliminarily.
I hope this helped you find your answer. Enjoy your day, and take care!
200 because 15 - 5 is 10 and 15+5 is 20. so 15 squared is 225 and 5 squared is 25 and 225-25 is 200
