Answer 1

If I’m not mistaken, the answer is C.

Answer 2

The answer is C.

Explanation:

In order to find the value of expression, you first have to solve x by substracting 6 to both sides then divide it by 5 :

`5x + 6 = 10`

`5x + 6 - 6 = 10 - 6`

`5x = 4`

`5x / 5 = 4 / 5`

`x = (4)/(5)`

Next, you have to substitute the value of x into the expression :

`let \: x = (4)/(5)`

`10x + 3`

`= 10( (4)/(5) ) + 3`

`= 8 + 3`

`= 11`
