Twice a number, added to seven, is the same

Mathematics
1 answer:
eduard2 years ago

Answer:

Your number is -10

Hope this helps :)

Step-by-step explanation:

Let x be the number

 

Twice a number is 2x

Added to 7 means + 7 so 2x + 7

Is means =

2x+7=

 

At this point I have to assume you mean

"is the same as three subtracted from THE SAME number"

Otherwise, rather than a number, we end up with the

equation of a line....

 

2x + 7 = x - 3   subtract x from both sides

x + 7 = -3        subtract 7 from both sides

x = -10

 

Your number is -10

 

Check:  2x+7 = x-3

           2(-10) + 7 = -10-3

           -20+7 = -13

            -13 = -13

            The answer fits the parameters of the problem.
