Answer:
2x + (x + 2)
Step-by-step explanation:
Let the number = x
"twice a number" means 2x
"increased by the sum of the same number and five" means to add x + 5, so the expression is
2x + (x + 2)
Simplify the following:
6 a b - 3 x + 2 a b
Grouping like terms, 6 a b - 3 x + 2 a b = -3 x + (6 a b + 2 a b):
-3 x + (6 a b + 2 a b)
a b 6 + a b 2 = 8 a b:
Answer: -3 x + 8 a b
