The unknown number will be (x)

2x+6=72

2x+6-6=72-6

2x/2=66/2

x=33

OR

x=(72-6)/2=33

Answer:

The number is 33.

Explanation:

A number: x

Twice a number: 2x

6 more than twice a number: 2x + 6

is: =

72: 72

Put it all together to get the equation:

2x + 6 = 72

Subtract 6 from both sides.

2x = 66

Divide both sides by 2.

x = 33
