- 3a - 1 = - 15
add 1 to each side
- 3a = - 14
divide each side by - 3 ( dividing a negative by a negative leaves a positive #)
a = 14/3
check
- 3(14/3) - 1 = - 15
- 15 = - 15

-21 = 9a - 15 - 3a -6 = 6a -1 = a
What is -3a equals -15?
12
How do you work out 3a plus 15 equals 4a?
3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.
If 3a - 9 equals 6 what is the value of 4a - 1?
3a-9 = 6 3a = 6+9 3a = 15 a = 15/3 a = 5 Substitute a = 5 into 4a-1. 4a-1 =4(5)-1 =20-1 =19 Therefore, the value of 4a-1 is 19.
What is 3a equals 1?
3a = 1a = 1/3 (a third)
What is the solutions to -3a-1 equals -15?
If: -3a-1 = -15 Then: a = 4 and 2/3
-3a - 1 equals -15?
a = 14/3

If 3a - 9 equals 6 what is the value of 4a - 1?
3a-9 = 6 3a = 6+9 3a = 15 a = 15/3 a = 5 Substitute a = 5 into 4a-1. 4a-1 =4(5)-1 =20-1 =19 Therefore, the value of 4a-1 is 19.
If 3a equals 1 what is the value of a?
3a=1divide both sides by 3a=1/3
What is 3a equals 1?
3a = 1a = 1/3 (a third)
-a plus 3a-2a equals?
1
What is the answer to 27-6a equals 3a?
1/3=a
