x plus 3 equals 7. This is the math problem. The answer is 4. This is basic pre-algebra/algebra. It's solving equations by adding or subtracting; therefore you must determine which value is the solution of the equation. If you can't figure this out by seventh/eighth grade, you need to ask your math teacher about it, because I'm 7th grade, and I'm moving on past pre-algebra soon.
