Add: (2m−3)+(3n−1)+(3m+1) .
To simplify the expression, we can combine like terms.
(2m−3)+(3n−1)+(3m+1)
Combining the terms with 'm', we have:
2m + 3m = 5m
Putting it back into the expression, we have:
5m − 3 + (3n − 1) + 1
Combining the terms with 'n', we have:
3n
Now, putting it back into the expression, we have:
5m − 3 + 3n − 1 + 1
Combining the constant terms, we have:
-3 - 1 + 1 = -3
Now, putting it back into the expression, we have:
5m + 3n - 3
Add: (2m−3)+(3n−1)+(3m+1) .
To simplify the expression, we can combine like terms:
(2m−3)+(3n−1)+(3m+1)
Using the distributive property, we can remove the parentheses:
2m - 3 + 3n - 1 + 3m + 1
Now, let's combine the like terms:
(2m + 3m) + (3n) + (-3 - 1 + 1)
Combining the terms with 'm':
5m + (3n) + (-3 - 1 + 1)
Combining the constant terms:
5m + 3n - 3
Therefore, the simplified expression is 5m + 3n - 3.
Subtract: 2(10b+4)−(b−2) .
To simplify the expression, we'll first distribute the 2 to the terms inside the parentheses:
2(10b+4)−(b−2)
= 20b + 8 - (b - 2)
Next, we'll remove the parentheses:
20b + 8 - b + 2
Now, we can combine like terms:
(20b - b) + (8 + 2)
= 19b + 10
Therefore, the simplified expression is 19b + 10.
Subtract: (3g−4)−2(3g+4)
To simplify the expression, we'll first distribute the -2 to the terms inside the parentheses:
(3g−4)−2(3g+4)
= 3g - 4 - 2*3g - 2*4
= 3g - 4 - 6g - 8
= (3g - 6g) + (-4 - 8)
= -3g - 12
Therefore, the simplified expression is -3g - 12.
