Answer:

a) 6c + 4d - c - 7d =  5c -3d

b) 3x + 5y - x + 2y =  2x + 7y

c) 3g + 5h + 4g - 2h =  7g + 3h

d) 8t + 3r - 7t - 9r = t - 6r

Step-by-step explanation:

combine like terms:

a) 6c + 4d - c - 7d =  5c -3d

b) 3x + 5y - x + 2y =  2x + 7y

c) 3g + 5h + 4g - 2h =  7g + 3h

d) 8t + 3r - 7t - 9r = t - 6r
