Create an equation for the following scenario: twice the sum of a number and 15 is equal to the difference between the same number and 6

Hey there! I'm happy to help!

Sum means you add. Let's call our number n.

n+15

We double the whole thing.

2(n+15)

This is equal to something.

2(n+15)=

Difference means you subtract.

2(n+15)=n-6.

Have a wonderful day! :D

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
