Answer:
5 (y + x) or c: 5x+y
Step-by-step explanation:
Simplify the following:
9 x - 3 y - 5 x + 7 y + x + y
Grouping like terms, 9 x - 3 y - 5 x + 7 y + x + y = (-3 y + 7 y + y) + (9 x - 5 x + x):
(-3 y + 7 y + y) + (9 x - 5 x + x)
-3 y + 7 y + y = 5 y:
5 y + (9 x - 5 x + x)
9 x - 5 x + x = 5 x:
5 y + 5 x
Factor 5 out of 5 y + 5 x:
Answer: 5 (y + x)
