Evaluate the expression (2x + y) + 5 when x = 4, y = 10.

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

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
