Answer 1

The sum of 38 and twice a number x is 124. The value of "x" is 43

- 2x - 5 is equal to – 91.

Solution:

Given that , The sum of 38 and twice a number x is 124.

We have to find what is - 2x - 5?

Now, according to given information, 38 + 2 × x = 124

2x + 38 = 124

2x = 124 – 38

2x = 86

x = 43

So, the value of x is 43

Now, Evaluating - 2x – 5

Substitute "x" = 43 to evaluate

- 2(43) – 5

- 86 – 5 = - 91

Hence, the required answer is – 91.
