Question

The value of 7a - 4b when a=3 b=2 is ​

Answer 1

We are given an expression 7a - 4b

And the values of a and b are given

a = 3 and b = 2

We have to find the value of the expression

Putting the given values in the expression

7a - 4b = 7(3) - 4(2)

            =21 - 8

            = 13

The value of the expression will be 13.

Answer 2

Given: the function$7a-4b$.

and$a=3,b=2$.

We have to find the value of the given function.

The given function is$7a-4b$.

Here, the values of$a$ and$b$ are given so by putting this values in the equation we can find the value of the equation.

$=>7a-4b\\=>7*3-4*2\\=>21-8\\=>13$

Hence, the value of the given function is $13.$
