It is the same as: 9a -4a = 5a
It is: 9a-a-a = 7a
If: 9a = 18b Then: a = 2b
The simplified expression is -9a -9b.
There is nothing you can do to 9a + 5 without knowing the value of a.
9a-99 = -90
It is: 9a-a-a = 7a
It is the same as: 9a -4a = 5a
9a - 8a = a
If: 9a = 18b Then: a = 2b
9a squared = 81a^2
9a verbal expression
9a+21 3(3a+7)
There is nothing you can do to 9a + 5 without knowing the value of a.
The simplified expression is -9a -9b.
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
-6 -9a = 16 : Add 6 to both sides -9a = 22 : Multiply both sides by -1 9a = -16 : Divide both sides by 9 a = -16/9 = -17/9
