Which of the following is not a way to represent the solution of the inequality 7 − 9x − (x + 12) less than or equal to 25? x greater than or equal to −3 x less than or equal to −3 −3 less than or equal to x a number line with a closed circle on negative 3 and shading to the right

did you ever get a answer?

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
