Answer:
Chase did not make a mistake.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS = Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.
First, multiply 3 to both sides:
(1/3)(g - 3) = 3
(3)(1/3)(g - 3) = 3(3)
g - 3 = 3 * 3
g - 3 = 9
Isolate the variable, g. Add 3 to both sides:
g - 3 (+3) = 9 (+3)
g = 9 + 3
g = 12
