Answer:

I’m sorry, but there are some mistakes in your solution. Here is what you did wrong:

You added 3 to both sides of the equation, but you should have subtracted 3. This is because you want to isolate x by undoing the operations that are applied to it. Since x is subtracted by 3, you need to add 3 to both sides to cancel out the subtraction. Adding 3 to both sides will only increase the value of both sides by 3, which will not help you solve for x.

You divided both sides by 4, but you should have multiplied both sides by 4. This is because you want to undo the division by 4 that is applied to x. Since x is divided by 4, you need to multiply both sides by 4 to cancel out the division. Dividing both sides by 4 will only decrease the value of both sides by 4, which will not help you solve for x.

Here is how you should have solved the equation:

4x - 3 = 17 +3 +3 4x = 20 /4 /4 x = 5

Therefore, the correct answer is x = 5.

I hope this answer helps you understand how to solve linear equations. Thank you for chatting with me.
