Question

3. Write an expression using the fewest terms possible that is equivalent to x+x+x+x-20

Answer 1

4x - 20

Explanation:

Combine like terms (those with the same amount of variables:

x + x + x + x = 4x

4x - 20 => Note: You cannot combine these two terms, because they do not have the same amount of variables (one having one variable (x), the other being a constant (no variable) ).
