This is very easy questions lets solve it
-2a - 9 = 39?
Add both site 9
-2a - 9 +9= 39+9
Now Simplyfy
-2a - 9 +9= 39+9
-2a= 48
devide both side with same factors
-2a/-2= 48/-2
a= -24
add 9 to both sides
-2a-9+9=39+9
then simplify
-2a=48
then divide both sides by the factor
-2a/-2 = 48/2
then simplify and you will get a = -24

2a-6a+9-4a+9
What is 2a - 1 equals 9?
2a - 1 = 9 Therefore, 2a = 10 a = 10/2 = 5 Therefore, a = 5.
What is -4 a 5 - 2a -9 44?
-4a+5-2a-9=44
How many students are there if there are seven more students than adults and there are a total of thity nine people?
s + a = 39 s - 7 =a s = a + 7 a + 7 + a = 39 2a + 7 = 39 2a = 32 a = 16 s + 16 = 39 s = 23 a + s = 39
What is 5a - a - 2a - 18?
assuming 5a-a-2a-18=0 2a-18=0 2a=18 and thus a=9
2a plus 21 equals 8a-9?
2a + 21 = 8a - 9Add 9 to each side:2a + 30 = 8aSubtract 2a from each side:30 = 6aDivide each side by 6:5 = a
2a-20 equals -2?
Simple algebra, 2a-20 = -2 2a=18 a=18/2 a=9
