Verified Answer :

d=3a+3b 
d-3a=3b 
(d-3a)/3=b

b=(d-3a)/3

Answer:

Value of \(b=\frac{d-3a}{3}\)

Step-by-step explanation:

Given the expression:

d = 3a+ 3b

Subtraction property of equality states that you subtract the same number to both sides of an equation.

Subtract 3a from both sides of an equation;

\(d -3a =3a + 3b -3a\)

Simplify:

\(d - 3a = 3b\)

Division property of equality states that you divide the same number to both sides of an equation.

\(\frac{d-3a}{3}=\frac{3b}{3}\)

Simplify:

\(\frac{d-3a}{3}=b\)

Therefore, the value of b is in terms of d and a;  \(b=\frac{d-3a}{3}\)
