Variable- A variable is a letter or a symbol that will represent a number in the equation.
In this case, the letter "X" is the variable.
Constant- In algebra a constant is a "fixed value," a number on its own in the equation.
In this equation the number "7" and "5" are the constants!
Co-efficient- When your number in the equation is being multiplied, divided, added, or subtracted by your variable.
In this equation, the number "5x" is the co-efficient.
