Question

Find the value of (3a + 2b – c) – (a + 7b – 5c ) + 14 if a = 3, b = -1, c=2

Answer 1

Answer:

33

Step-by-step explanation:

let's assign values to the equation,

=(3a+2b-c) - (a+7b-5c) + 14

= (3(3)+2(-1)-2) - (3+7(-1)-5(2)) + 14

= (9+(-2)-2) - (3+(-7)-10) + 14

= (9-2-2) - (3-7-10) + 14

= (5) - (-14) + 14

= 33
