If the values were correct, then the equation would be correct. That's why you solve. for example 2x+5=4x-3. You would know that 4 would be the best value for the equation because you solved it. If you're not sure, try replacing the variable with your solved value(s).

2(4)+5=4(4)-3
8+5=16-3
13=13

and there you have it
