How do you work out 3a plus 15 equals 4a?
3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.
How do you solve -21 equals 9a-15-3a?
-21 = 9a - 15 - 3a -6 = 6a -1 = a
What is the answer to -3a - 1 equals -15?
- 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
How do you solve -2a plus 5 plus 3a equals 15-21?
depends what 'a' =
The absolute value of 6 plus 3a equals 15?
Subtract 6 from each side: 3a = 9Divide each side by 3: a = 3Job done.
How do you work out 3a plus 15 equals 4a?
3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.
What is the answer to -3a equals 15?
a = -5
What is the solutions to -3a-1 equals -15?
If: -3a-1 = -15 Then: a = 4 and 2/3
How do you solve -21 equals 9a-15-3a?
-21 = 9a - 15 - 3a -6 = 6a -1 = a
-3a - 1 equals -15?
a = 14/3
What is the answer to -3a - 1 equals -15?
- 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
How do you solve -2a plus 5 plus 3a equals 15-21?
depends what 'a' =
The absolute value of 6 plus 3a equals 15?
Subtract 6 from each side: 3a = 9Divide each side by 3: a = 3Job done.
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 The answer for -3a-12 equals 12?
-3a-12 = 12+12 +12-3a = +12~ ~-3 -3a = -8
What is 3a equals 1?
3a = 1a = 1/3 (a third)
