x + 12 = -12
You solve the equation.
3 or 4.
Let's represent the number as "x". The given equation can be written as 2x - 12 = 30. Adding 12 to both sides, we get 2x = 42. Finally, dividing both sides by 2, we find that x = 21. So, the number is 21.

Number of neutrons = mass number - number of protons
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.
