Question

Twice the difference of a number and 3 equals 2 use the variable c for the unknown number.

Answer 1

The number is 4

Step-by-step explanation:

First of all we have to convert the given statement in mathematical form.

Let c be the number then according to given statement

$2(c-3) = 2$

We have to isolate the variable in the equation

Dividing both sides by 2

$\frac{2(c-3)}{2} = \frac{2}{2}\\c-3 = 1$

Adding 3 on both sides

$c-3+3 = 1+3\\c = 4$

Hence,

The number is 4
