Answer: John’s calculations are not correct. He compared the exact value to the absolute error. The absolute error should be in the numerator and the exact value in the denominator.

Isolate the w. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, multiply 4/3 to both sides

(3/4)(4/3)(8w - 12) = 3(4/3)

8w - 12 = (12/3)

8w - 12 = 4

Isolate the w. Add 12 to both sides

8w -12 (+12) = 4 (+12)

8w = 4 + 12

8w = 16

Finally, to completely isolate the w, divide 8 from both sides

8w/8 = 16/8

w = 16/8

w = 2

2 is your answer for w

hope this helps
