What is -2a+7-3(-9-4a)
Multiply (-3 x -9) and (-3 x -4a)
-2a+7+27+12a
Now collect like terms
10a+34
-2a+7-3(-9-4a)
-2a + 7 + 27 + 12a
10a + 34
To simplify the expression -2a + 7 - 3(-9 - 4a), we can start by applying the distributive property.
First, distribute the -3 to both terms inside the parentheses (-9 and -4a):
-3(-9 - 4a) = -3 * -9 - 3 * -4a
Multiply -3 by -9:
27 - 3 * -4a
Multiply -3 by -4a:
27 + 12a
Now, we can rewrite the original expression with the simplified terms:
-2a + 7 + 27 + 12a
Combine the 'a' terms:
(-2a + 12a) + 7 + 27
Simplify the 'a' terms:
10a + 7 + 27
Combine the constant terms:
10a + 34
Therefore, the simplified expression is 10a + 34.
