Answer:
2x + 7y and 7g + 3h
Step-by-step explanation:
(a)
3x + 5y - x + 2y ← collect like terms
= (3x - x) + (5y + 2y)
= 2x + 7y
(b)
3g + 5h + 4g - 2h ← collect like terms
= (3g + 4g) + (5h - 2h)
= 7g + 3h
A) 2x + 7y
B) 7g + 3h
A) 3x + 5y - x +2y =
3x - x = 2x
5y + 2y = 7y ans: 2x + 7y
B) 3g + 5h +4g - 2h =
3g + 4g = 7g
5h - 2h = 3h ans: 7g + 3h
