.Let's say you solve an equation like 3x + 5 = x + 7 and your solution is x = 1. How could you check to make sure your answer is correct?

plug in whatever you found for x and see if its equal on both sides.

Step-by-step explanation:

To check an answer for an equation, you can substitute the answer you've found in place of the variable you solved it for.

The value of the unknown, x, can be plugged into the equation. You can then compare both sides to see if they are equal.

For your given equation, let's substitute 1 for x in the equation you've given.

3x + 5 = x + 7

3(1) + 5 = 1 +7

Simplify this.

3 + 5 = 8

8 = 8

You know that 8 does equal 8, so your value for x is correct.

I hope this helps you ^^

Good luck :)
