1)  

 (13d - 3z) from (-5d + 26z)

- Answer: 18d

Answer: 29z


SOLUTION 1 :

   (-5d + 26z) - (13d - 3z)

   =   - 5d + 26z - 13d + 3z

   =   (- 5d - 13d) +  (26z + 3z)

   =  (- 5 - 13)d + (26 + 3)z 

   = (- 18)d + (29)z

    = - 18d + 29z

 



2)  

 (17o - 11w) from (-5o + 18w)

- Answer: 22o

Answer: 29w


SOLUTION 1 :

   (-5o + 18w) - (17o - 11w)

   =   - 5o + 18w - 17o + 11w

   =   (- 5o - 17o) +  (18w + 11w)

   =  (- 5 - 17)o + (18 + 11)w 

   = (- 22)o + (29)w

    = - 22o + 29w

 



3)  

 (16k - 2q) from (-6k + 13q)

- Answer: 22k

Answer: 15q


SOLUTION 1 :

   (-6k + 13q) - (16k - 2q)

   =   - 6k + 13q - 16k + 2q

   =   (- 6k - 16k) +  (13q + 2q)

   =  (- 6 - 16)k + (13 + 2)q 

   = (- 22)k + (15)q

    = - 22k + 15q

 



4)  

 (13f - 10x) from (-2f + 21x)

- Answer: 15f

Answer: 31x


SOLUTION 1 :

   (-2f + 21x) - (13f - 10x)

   =   - 2f + 21x - 13f + 10x

   =   (- 2f - 13f) +  (21x + 10x)

   =  (- 2 - 13)f + (21 + 10)x 

   = (- 15)f + (31)x

    = - 15f + 31x

 



5)  

 (18w - 3t) from (-7w + 14t)

- Answer: 25w

Answer: 17t


SOLUTION 1 :

   (-7w + 14t) - (18w - 3t)

   =   - 7w + 14t - 18w + 3t

   =   (- 7w - 18w) +  (14t + 3t)

   =  (- 7 - 18)w + (14 + 3)t 

   = (- 25)w + (17)t

    = - 25w + 17t

 



6)  

 (20n - 9o) from (-6n + 26o)

- Answer: 26n

Answer: 35o


SOLUTION 1 :

   (-6n + 26o) - (20n - 9o)

   =   - 6n + 26o - 20n + 9o

   =   (- 6n - 20n) +  (26o + 9o)

   =  (- 6 - 20)n + (26 + 9)o 

   = (- 26)n + (35)o

    = - 26n + 35o

 



7)  

 (25m - 2c) from (-6m + 26c)

- Answer: 31m

Answer: 28c


SOLUTION 1 :

   (-6m + 26c) - (25m - 2c)

   =   - 6m + 26c - 25m + 2c

   =   (- 6m - 25m) +  (26c + 2c)

   =  (- 6 - 25)m + (26 + 2)c 

   = (- 31)m + (28)c

    = - 31m + 28c

 



8)  

 (13i - 7v) from (-9i + 27v)

- Answer: 22i

Answer: 34v


SOLUTION 1 :

   (-9i + 27v) - (13i - 7v)

   =   - 9i + 27v - 13i + 7v

   =   (- 9i - 13i) +  (27v + 7v)

   =  (- 9 - 13)i + (27 + 7)v 

   = (- 22)i + (34)v

    = - 22i + 34v

 



9)  

 (18a - 8w) from (-6a + 15w)

- Answer: 24a

Answer: 23w


SOLUTION 1 :

   (-6a + 15w) - (18a - 8w)

   =   - 6a + 15w - 18a + 8w

   =   (- 6a - 18a) +  (15w + 8w)

   =  (- 6 - 18)a + (15 + 8)w 

   = (- 24)a + (23)w

    = - 24a + 23w

 



10)  

 (22j - 2z) from (-9j + 13z)

- Answer: 31j

Answer: 15z


SOLUTION 1 :

   (-9j + 13z) - (22j - 2z)

   =   - 9j + 13z - 22j + 2z

   =   (- 9j - 22j) +  (13z + 2z)

   =  (- 9 - 22)j + (13 + 2)z 

   = (- 31)j + (15)z

    = - 31j + 15z
