Alejandro loves to go to the movies .He goes both at night and during the he day
Alex17521 [72]

The number of matinee movies attended is 4.

The number of a evening show movies attended is 2.

<u>Step-by-step explanation:</u>

  • Let x represent the number of matinee movies attended.
  • Let y represent  the number of evening show movies attended.
  • Alejandro went to see a total of 6 movies.

Therefore, from the given data the equation can be framed as :

⇒ x + y = 6  ----------(1)

  • The cost of a matinee is $7.
  • The cost of an evening show is $12.
  • Alejandro spent a total of $52.

Therefore, from the given data the equation can be framed as :

⇒ 7x + `12y = 52  ---------(2)

<u>To solve the equations for x and y values :</u>

Mulitply eq (1) and by 7 and subtract eq (2) from eq (1),

  7x + 7y = 42

- <u>(7x + 12y = 52)</u>

  <u>     - 5y = - 10 </u>

⇒ y = 10/5

⇒ y = 2

The number of a evening show movies attended is 2.

Substitute y=2 in eq (1),

⇒ x+2 = 6

⇒ x = 6-2

⇒ x = 4

The number of matinee movies attended is 4.
