Solve for x. −ax + 4b > 9 a. x > the quantity 4 times b minus 9 all over a b. x the quantity 4 times b plus 9 all over negative a

Answers

B.

-ax >9 -4b
x < (9-4b)/a

-5b
is the the answer
- b - 4b = - 5b

bold{x < dfrac{4b-9}{3}}

Step-by-step explanation:

-3x + 4b > 9

       -4b  -4b  

-3x        > -4b + 9

÷-3       ↓    ÷-3    

  x         <dfrac{-4b+9}{-3}

  x         <dfrac{-1(4b-9)}{-1(3)}

  x         <dfrac{4b-9}{3}

The answer is the first option: 1) x> the quantity 4 times b minus 9 all over a

The explanation is shown below:

1. To solve this problem you must pply the following proccedure:

2. Move the term4b to the left member. As the variable is negative, multiply the expression by-1 and change the direction of the sign:
