Solve the given system by substitution. c = -3b c=4/3b-13

Question

b = 3; c = −9

b = −9; c = −3

b = −1; c = −9

b = −3; c = −1

a b c d

pls tell me which 1 a b c or d

Answer 1

c=-3b = (4/3)b - 13

(4/3 +3)b = 13

13b/3 = 13

b= 3

c =-3(3) = -9

(b,c) = (3,-9)

answer a) is correct

Unless you really meant

c= 4/(3b) -13 or c=4/(3b-13)

then none of the answers are correct
