Question

If 3 is added to twice a number, the result is 17. Find the number

Answer 1

Answer:

7

Step-by-step explanation:

The text of this expression is:

"If 3 is added to twice a number, the result is 17. Find the number"

Let's call $x$ the number we want to find.

Twice the number is equal to

$2x$

So, if we add 3 to 2x, we get

$3+2x$

And we know that this is equal to 17:

$3+2x=17$

Now we can solve the equation to find x: first, we subtract 3 from both sides

$3+2x-3=17-3\\2x=14$

Now we divide both sides by 2:

$\frac{2x}{2}=\frac{14}{2}\\x=7$
