Subtract: 2(10b+4)−(b−2) .
To subtract 2(10b+4)−(b−2), first apply the distributive property by multiplying 2 by each term inside the parentheses:
2(10b+4) = 20b + 8
Now we can rewrite the expression as:
20b + 8 - (b - 2)
To subtract the expressions inside the parentheses, distribute the negative sign to each term within the parentheses:
20b + 8 - b + 2
Now combine like terms:
(20b - b) + (8 + 2)
simplifies to:
19b + 10
To subtract (3g−4)−2(3g+4), first apply the distributive property by multiplying 2 by each term inside the parentheses:
2(3g + 4) = 6g + 8
Now we can rewrite the expression as:
(3g - 4) - (6g + 8)
To subtract the expressions inside the parentheses, distribute the negative sign to each term within the second set of parentheses:
3g - 4 - 6g - 8
Now combine like terms:
(3g - 6g) + (-4 - 8)
simplifies to:
-3g - 12
Subtract: (3g−4)−2(3g+4)

To subtract the expression 2(10b+4)−(b−2), we will simplify each term and combine like terms.
Step 1: Distribute the 2 to both terms inside the parentheses:
2(10b+4) = 20b + 8
Step 2: Distribute the negative sign to both terms inside the parentheses:
-(b−2) = -b + 2
Now, we can combine the simplified terms:
20b + 8 - (-b + 2)
Step 3: When subtracting a negative number, we can rewrite it as addition:
20b + 8 + b - 2
Step 4: Combine like terms:
(20b + b) + (8 - 2)
Step 5: Simplify:
21b + 6
Therefore, the final simplified expression is 21b + 6.
To subtract the given expression:
2(10b+4)−(b−2), we need to distribute the 2 through the first parentheses first:
2 * 10b = 20b
2 * 4 = 8
Therefore, the expression becomes:
20b + 8 - (b - 2)
Now, we can remove the parentheses by changing the signs inside the parentheses:
20b + 8 - b + 2
Next, we combine like terms:
(20b - b) + (8 + 2)
19b + 10
The final expression after subtraction is 19b + 10.
