If: 9a = 18b
Then: a = 2b
It is: 9a-a-a = 7a
The expression (9a - a - a) simplifies to (9a - 2a), which equals (7a). So, the final result is (7a).
2a+5a+9a = 16a
-14 + 9a = 389a = 52a = 52/9 or 5.78
-21 = 9a - 15 - 3a -6 = 6a -1 = a
It is: 9a-a-a = 7a
The expression (9a - a - a) simplifies to (9a - 2a), which equals (7a). So, the final result is (7a).
9a+21 3(3a+7)
2a+5a+9a = 16a
-14 + 9a = 389a = 52a = 52/9 or 5.78
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
-21 = 9a - 15 - 3a -6 = 6a -1 = a
-a^2- 9a - 18 = 0 -(a^2 + 9a + 18) = 0 -(a + 6)(a + 3) = 0
9a + 4a = 26 13a = 26 a = 26/13 a = 2
The expression "9a plus 1" can be written mathematically as (9a + 1). This represents a linear equation where (a) is a variable. The value of the expression depends on the value of (a). For example, if (a = 2), then (9a + 1) equals (19).
4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
a= -4
