So we have 5a + 11 + 3a - 7 = -4 Start by combining common terms such as the 5a and 3a to give you 8a and 11 and -7 to give you 4. So now your equation is 8a + 4 = -4. Subtract 4 from both sides gives you 8a = -8. Divide -8 by 8 to give you a = -1, your solution.
No. 3a 12 plus a 6 is not a solution Of an equation.
If a + b = 6, what is the value of 3a + 3b?
Subtract 8 from each side: 3a = 33 Divide each side by 3: a = 11
a + a + a - 2a = 3a - 2a = a
a = 20
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
1a (or just a for short).
No. 3a 12 plus a 6 is not a solution Of an equation.
What is the solution of -2a plus 3a plus 5b
If a + b = 6, what is the value of 3a + 3b?
Subtract 8 from each side: 3a = 33 Divide each side by 3: a = 11
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
a + 3a + 5a = 180 9a =180 a = 20
2a + 3a + 4 = 5a + 4
The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.
a + a + a - 2a = 3a - 2a = a
