Answer:

3P= 3a+3b+c

3b=3a+c-3P

b= (3a+c-3P)/3

b= (3a)/3+c/3-(3P)/3

b= a+c/3-P

Explanation:

let the expression with b be on one side of the equation while you send the other expressions to the other side of the equation.

now, divide through the equation with the coefficient of b which is 3.

simplify the equation by making b the subject of the equation
