The value of (3x+4y) is 15

Given : The given values are, x = 5 and y = 0

To find : The value of (3x+4y)

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the value of the said algebraic expression)

Here, we just need to put the given values of x and y in the given algebraic expression. Rest of the problem is based on general calculations only.

So,

= (3x+4y)

= (3×5) + (4×0) [Putting the given values]

= 15 + 0

= 15

(This will be considered as the final result.)

Hence, the value of (3x+4y) is 15
