Question

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

Answer 1

Answer:

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

Answer 2

Answer:

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
