The answer is 45
Solution:
Given expression is 4x + 5 + 2x + y.
To find the value of this expression when x = 6 and y = 4.
Substitute x = 6 and y = 4 in the given expression.
4x + 5 + 2x + y = 4(6) + 5 + 2(6) + 4
= 24 + 5 + 12 + 4
= 45
4x + 5 + 2x + y = 45
Hence, the value of 4x + 5 + 2x + y if x = 6 and y = 4 is 45.
