Question

Seven subtracted from twice a number gives 17. An equation for the same is *​

Answer 1

Answer:

7 - 2x = 17

2x = 17 - 7

2x = 10

x = 10/2

x = 5

Answer 2

Given,

Seven subtracted from twice a number = 17.

To find,

The equation for the given condition.

Solution,

Firstly, let the required number be x.

Now, we have to find twice this number and then subtract 7 from the result obtained.

So, twice this number will be 2x.

Now, subtracting 7 from 2x, we get the following expression.

2x - 7.

It is given that 17 is obtained after applying the given condition. So, the above expression should equal 17. Hence,

2x - 7 = 17, which is the required equation.

Therefore, an equation for "seven subtracted from twice a number gives 17", will be 2x - 7 = 17.
