Answer:

The answer is 40

Step-by-step explanation:

Let x = the vaue has to be found i.e. 5bc - 2a

Since tthe given values in question, so put the values as :

x = 5bc - 2a

x  = 5 (-3 × -4)  - 2 (10)

x  = 5 (12)  - 20   [inside multiplication]

x  = 60  - 20

x  = 40

Hence the answer of 5bc - 2a is 40

Answer: 5bc-2a = 40

a =10 ; b= -3 ;  c= -4

5bc-2a =  (5 *b * c) - (2 * a)           (Substitute values in the equation)

            = (5 * -3 * -4) - (2 * 10)      ( Product of 2 negative numbers is positive)

            = (5 * 12) - 20

            = 60 - 20 = 40
