Answer:
The value of 7a+4b-2c is 30.
Solution:
Given,
Value of a = 8 ----- (1)
Value of b = 2 ----- (2)
Value of c = 17 ----- (3)
To find the value of the given equation, [tex]7a+4b-2c[/tex] ----- (4)
Substituting (1), (2) and (3) in (4) we get,
[tex]7\times8 + 4\times2 - 2\times17[/tex]
On multiplying the terms we get,
[tex]56+8-34 = 64-34 = 30[/tex]
So, the value of the given equation is 30.
