    The answer is 23.

    Step-by-step explanation:

    Our equation here is (2x + y) + 5.

    If x=4, and y=10, let's plug that in into our variables, and simplify!

    [2 (4) + (10) ] + 5

    = [8+10] + 5

    =[18] + 5

    =23

    23

    Step-by-step explanation:

    The question is a under substitution, that's a given number will be used to replace a letter

    So back to the question

    (2x+y) + 5

    And x is said to be 4 and y is 10

    Let's start solving

    (2 (4) + 10) + 5

    Hope you understand it to this extent, any where you see x you will have to put the given value for x same goes for y

    (8+10) + 5

    18+5

    23

    Therefore the evaluation is 23
