Answer:
Value of [tex]b=\frac{d-3a}{3}[/tex]
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;
[tex]d -3a =3a + 3b -3a[/tex]
Simplify:
[tex]d - 3a = 3b[/tex]
Division property of equality states that you divide the same number to both sides of an equation.
[tex]\frac{d-3a}{3}=\frac{3b}{3}[/tex]
Simplify:
[tex]\frac{d-3a}{3}=b[/tex]
Therefore, the value of b is in terms of d and a; [tex]b=\frac{d-3a}{3}[/tex]
