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
