1)  

Solve the expressions,

add: 24F - 13Z, 5Z - 6F + 19 

Answer: 18F

- Answer: 8Z

Answer: 19


SOLUTION 1 :

  (24F -13Z) + (5Z -6F + 19)

    = 24F -13Z + 5Z -6F + 19

    = (24F -6F) + (-13Z + 5Z) + 19

    = (24- 6)F + (-13 + 5)Z + 19

    = 18F - 8Z + 19



2)  

Solve the expressions,

add: 22I - 15N, 6N - 2I + 11 

Answer: 20I

- Answer: 9N

Answer: 11


SOLUTION 1 :

  (22I -15N) + (6N -2I + 11)

    = 22I -15N + 6N -2I + 11

    = (22I -2I) + (-15N + 6N) + 11

    = (22- 2)I + (-15 + 6)N + 11

    = 20I - 9N + 11



3)  

Solve the expressions,

add: 11O - 25C, 3C - 8O + 7 

Answer: 3O

- Answer: 22C

Answer: 7


SOLUTION 1 :

  (11O -25C) + (3C -8O + 7)

    = 11O -25C + 3C -8O + 7

    = (11O -8O) + (-25C + 3C) + 7

    = (11- 8)O + (-25 + 3)C + 7

    = 3O - 22C + 7



4)  

Solve the expressions,

add: 18S - 26Y, 4Y - 7S + 19 

Answer: 11S

- Answer: 22Y

Answer: 19


SOLUTION 1 :

  (18S -26Y) + (4Y -7S + 19)

    = 18S -26Y + 4Y -7S + 19

    = (18S -7S) + (-26Y + 4Y) + 19

    = (18- 7)S + (-26 + 4)Y + 19

    = 11S - 22Y + 19



5)  

Solve the expressions,

add: 22A - 17W, 3W - 2A + 22 

Answer: 20A

- Answer: 14W

Answer: 22


SOLUTION 1 :

  (22A -17W) + (3W -2A + 22)

    = 22A -17W + 3W -2A + 22

    = (22A -2A) + (-17W + 3W) + 22

    = (22- 2)A + (-17 + 3)W + 22

    = 20A - 14W + 22



6)  

Solve the expressions,

add: 23B - 23D, 10D - 3B + 21 

Answer: 20B

- Answer: 13D

Answer: 21


SOLUTION 1 :

  (23B -23D) + (10D -3B + 21)

    = 23B -23D + 10D -3B + 21

    = (23B -3B) + (-23D + 10D) + 21

    = (23- 3)B + (-23 + 10)D + 21

    = 20B - 13D + 21



7)  

Solve the expressions,

add: 17R - 20X, 9X - 4R + 21 

Answer: 13R

- Answer: 11X

Answer: 21


SOLUTION 1 :

  (17R -20X) + (9X -4R + 21)

    = 17R -20X + 9X -4R + 21

    = (17R -4R) + (-20X + 9X) + 21

    = (17- 4)R + (-20 + 9)X + 21

    = 13R - 11X + 21



8)  

Solve the expressions,

add: 15M - 14J, 8J - 5M + 2 

Answer: 10M

- Answer: 6J

Answer: 2


SOLUTION 1 :

  (15M -14J) + (8J -5M + 2)

    = 15M -14J + 8J -5M + 2

    = (15M -5M) + (-14J + 8J) + 2

    = (15- 5)M + (-14 + 8)J + 2

    = 10M - 6J + 2



9)  

Solve the expressions,

add: 12C - 13W, 9W - 7C + 6 

Answer: 5C

- Answer: 4W

Answer: 6


SOLUTION 1 :

  (12C -13W) + (9W -7C + 6)

    = 12C -13W + 9W -7C + 6

    = (12C -7C) + (-13W + 9W) + 6

    = (12- 7)C + (-13 + 9)W + 6

    = 5C - 4W + 6



10)  

Solve the expressions,

add: 16V - 15B, 7B - 6V + 8 

Answer: 10V

- Answer: 8B

Answer: 8


SOLUTION 1 :

  (16V -15B) + (7B -6V + 8)

    = 16V -15B + 7B -6V + 8

    = (16V -6V) + (-15B + 7B) + 8

    = (16- 6)V + (-15 + 7)B + 8

    = 10V - 8B + 8
