Answer: -4
This is because -4 is closer to 0 on the number line, when compared to -5.
You are basically measuring the distances from 0 to determine magnitude.
The answer is (1,5) and (4,20) they make both of the equations true
An expression becomes an equation by adding an equal sign to the end of the expression and if there's a number on the other side of the equation. For example, 4+3 becomes an equation if you put 4+3=7. Or, 4+3=2+5. Good luck!
