Question

The difference of twice a number and 2 is -21

Answer 1

Answer:

2x-2= -21

Step-by-step explanation:

Answer 2

Answer:

-9.5

Step-by-step explanation:

We can create an equation to represent this, where $n$ is the missing value.

$2n - 2 = -21$

Now we can solve for $n$ by isolating it on one side of the equation.

Add 2 to both sides:

$2n - 2 + 2 = -21+2\\\\2n = -19$

Divide both sides by 2:

$2n\div2 = -19\div2\\\\n = -9.5$
