Given the numerical expression:
5b+3c-20+3b-15c+4
Evaluate when,
b = 2
c = -3
Solution:
In order to evaluate the numerical expression, we simply need to substitute the values of 2 and -3 to the equation.
= 5(2) + 3(-3) - 20 + 3(2) + 15(-3) + 4
Simplify and combine all the values.
= 10 - 9 - 20 + 6 - 45 + 4
= 1 - 14 - 41
= - 54
Final answer:
= -54
