Answer:
x = (b + 5/a)
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 5 to both sides of the equation:
ax - 5 (+5) = b (+5)
ax = b + 5
Next, divide a from both sides to isolate the variable, x:
(ax)/a = (b + 5)/a
x = (b + 5)/a
x = (b + 5/a) is your answer.
