For the equation 2x + 7 =30, x = 3
O True
O False

 False

Explanation:

To see if the x value is a solution or not, we plug it into the equation given

2x+7 = 30 original equation

2*3 + 7 = 30 replace every x with 3, since we claim that x = 3

6 + 7 = 30 multiply 2 and 3 to get 6

13 = 30 add 6 and 7 to get 13

We get two different numbers on either side, so the last equation is not true. We get a contradiction or false statement. So the original equation is false when x = 3. Therefore, x = 3 is not the solution.

That's why the overall claim is false.
