So let's break down this equation:
The difference -> this means its going to be a subtraction problem.
of twice a number and five -> 2n - 5
is 3 -> = 3 . Remember that "is" can be translated into an equal sign.
Putting our equation together, its 2n - 5 = 3.
Next, to solve an equation you want to isolate the variable. In this case, you have to add 5 on both sides then multiply by 1/2, or C, to solve the equation.
