think of a number. double the number, subtract 6 from the result and divide answer by 2. the quotient will be 20. what is the number? show you solution pls.

Respuesta :

Let x = the unknown number. (2x - 6) divided 2 = 20
Multiply both sides of the equation by 2
2x - 6 = 40  then add 6 to both sides,
2x = 46  divide both sides by 2
x = 23
