-14 + 9a = 38
9a = 52
a = 52/9 or 5.78
2a+5a+9a = 16a
a= -0.8
a= -4
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).
Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3
2a+5a+9a = 16a
9a+21 3(3a+7)
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
a= -0.8
a= -4
a is equal to 1.
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).
9a + 4a = 26 13a = 26 a = 26/13 a = 2
Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3
9a plus a equals 10a. You can combine the like terms by adding the coefficients of 'a' together: 9 + 1 = 10. Therefore, the expression simplifies to 10a.
4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
a + 3a + 5a = 180 9a =180 a = 20
