Select the term that can be combined with the term: 3x.

Select the term that can be combined with the term: 2y

Find the Sum: 
(5 - t) + (3t +2)

• 2t + 7

• 2t + 3

• -2t + 3

• -2t + 7

Add these expressions: (x + 5) + (2x + 10)

• 3x + 15

• x - 5

• 18x

Find the sum:
(7k + 9) + (4k - 3)

• 3k + 6 

• 11k + 6

• -11k + 6

• - 3k + 6

(-11a + 7) – (11a – 7)

• -22a - 14

• 0

• -22a + 14

• -22a

2(2x + 3) + 3(4x + 5)

• 6x + 8
