Answer:

5.) b

6.)a

Step-by-step explanation:

5.) b

3x - 24 = 81 (add 24 on both sides)

3x = 105 (divide by 3 on both sides)

x = 35 or 105/3

6.) a

-5x - 25 = 78 (1st add 25 on both sides)

-5x = 103 (2nd divide both sides by -5)

x = -20.6

Hope this helps ya!!

One month Pablo rented 12 movies and 2 video games for a total of $65. The next month he rented 3 movies and 5 video games for a
borishaifa [10]

The rent for one movie is $4.50 and rent for one video game is $5.50

Step-by-step explanation:

Let,

Rent for one movie = x

Rent for one video game = y

According to given statement;

12x+2y=65     Eqn 1

3x+5y=41        Eqn 2

Multiplying Eqn 2 by 4

4(3x+5y=41)\\12x+20y=164\ \ \ \ Eqn\ 3

Subtracting Eqn 1 from Eqn 3

(12x+20y)-(12x+2y)=164-65\\12x+20y-12x-2y=99\\18y=99\\

Dividing both sides by 18

\frac{18y}{18}=\frac{99}{18}\\y=5.50

Putting y=5.50 in Eqn 2

3x+5(5.50)=41\\3x+27.50=41\\3x=41-27.50\\3x=13.50

Dividing both sides by 3

\frac{3x}{3}=\frac{13.50}{3}\\x=4.50

The rent for one movie is $4.50 and rent for one video game is $5.50
