Twice the difference of a number and 2 is 8 use the variable c for the unknown number.

I believe this equation would be written as:

2(c - 2) = 8.

(Bonus) The answer to the equation is 6. 6 - 2 = 4 2 x 4 = 8

this equation would be written as:

2(c - 2) = 8.

(Bonus) The answer to the equation is 6. 6 - 2 = 4 2 x 4 = 8
