Follow PEMDAS - but backwards.
(Parenthesis, Exponents. Multiplication, Division, Addition, Subtraction)
First SUBTRACT 5 from each side of the equation...
3x/5 + 5 (- 5) = 20 (- 5)
3x/5 = 15
Next MULTIPLY each side by 5...
3x/5 ( • 5) = 15 (• 5)
3x = 75
The third step if you need is to DIVIDE ...
3x ( / 3) = 75 (/ 3)
x = 25
The answer to the question is 2.)2.5 because when you substitute 12/7 into the inequality you get 20 which is not greater than 20 and when you substitute -3 you get -13 which is also not greater then 20 but when you substitute 2.5 you get 25.5 which is greater than 20
