Twice the difference of a number 3 and is equal to 2 .

Question

I really need help with this sentence that i cant solve.

Answer 1

Call the number  n; then the "difference of a number AND 3" (note word that was missing in your statement of the problem) is (n - 3)

 

so the statement can be translated into  2(n - 3) = 2.   ⇐ Twice the ... means multiply the following by 2

 

I'll bet that you CAN solve this equation.
