Question

What is the value of b, in terms of c and d ? a-b= c 2a+b= -d

Answer 1

Answer:

0b = d ; b= (-2/3)c

Step-by-step explanation:

b = a-c

b= -d-2a

Therefore

a-c = -d -2a

3a = c-d

a = (c-d)/3

(c-d)/3-c = -d -2((c-d)/3)

-2c-d/3  = -d +(-2c-2d)/3

-2c-d = -2c -5d

0 = -4d

d = 0

Therefore

2a+ b= 0

b = -2a                       equation 1

therefore,

a - (-2a) = c

3a=c

a=c/3

therefore,

b = (-2/3)c   &  0b=d
