Answer:

$- 3(4x - 8) = - 36 \\ 4x - 8 = \frac{ - 36}{ - 3} \\ 4x - 8 = 12 \\ 4x = 12 + 8 \\ 4x = 20 \\ x = 20 \div 4 \\ x = 5$

Answer:

Step-by-step explanation:

(given) -3(4x - 8) = -36

(distribute) -12x + 24 = -36

(subtract 24 from both sides) -12x = -60

(divide both sides by -12) x = 5

What is 9c+90<-27?????

antoniya [11.8K]

<h3>Answer: c < -13</h3>

========================================

Work Shown:

9c + 90 < -27

9c + 90 - 90 < -27 - 90 .... see note 1

9c < -117

9c/9 < -117/9 ... see note 2

c < -13

-----------

note 1: I'm subtracting 90 from both sides to undo the "plus 90" that is happening on the left side

note 2: I divided both sides by 9 to undo the multiplication. The expression 9c is the same as 9*c or "9 times c". The inequality sign will <u>not</u> flip as we are dividing both sides by a positive number.
