The difference between twice a number and 23

Question

I don’t know what this means please help

Answer 1

I believe it just wants you to right an equation.

Difference means subtraction.

Twice means multiply by 2.

2x-23

Normally, you would set that equal to something; either a variable or an actual value so I'll use a variable y

y=2x-23

I wrote in the order the sentence was written.
