To subtract, we distribute and then combine like terms:
2(10b + 4) - (b - 2)
= 20b + 8 - (b - 2) [distributing 2 to both terms in parentheses]
= 20b + 8 - b + 2 [distributing -1 to both terms in parentheses]
= 19b + 10 [combining like terms]
Therefore, 2(10b + 4) - (b - 2) simplifies to 19b + 10.
2(10b + 4) - (b - 2)
= 20b + 8 - (b - 2) [distributing 2 to both terms in parentheses]
= 20b + 8 - b + 2 [distributing -1 to both terms in parentheses]
= 19b + 10 [combining like terms]
Therefore, 2(10b + 4) - (b - 2) simplifies to 19b + 10.
