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
Step-by-step 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
