Answer:
the answer is b= r/m - 4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
The expression r = (4 + b)m can be solved for b and b = (r - 4m)/m after simplification.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
We have an expression:
r = (4 + b)m
To solve for b make the subject b
Divide both sides by m; m ≠ 0
r/m = 4 + b
b = r/m - 4
b = (r - 4m)/m
Thus, the expression r = (4 + b)m can be solved for b and b = (r - 4m)/m after simplification.
