A = 5b + 8 rearrange the formula to make b the subject

b = (a-8) / 5

Step-by-step explanation:

we have given the equation a = 5b+8

First step we will do is to shift 8 on left hand side of the equation positive 8 will become negative 8after shifting the equation will become a-8=5b

Next we will shift 5 on left hand side of the equation since, on right hand side it is in multiply with the variable when shifted to left hand side it changes to divide

Finally the equation will change having "b" as a subject

b = (a-8) / 5

Solve for b by simplifying both sides of the equation, then isolating the variable.

b = - 8/5 + a/5
