13a - 6 + a = 5a + 3 + 3a

13a + a - 5a - 3a = 3 + 6

6a = 9

6a/6 = 9/6

a = 3/2

Q: What is the value of a in 13a - 6 plus a equals 5a plus 3 plus 3a?

If a + b = 6, what is the value of 3a + 3b?

12

2a + 7b = -13a - 7b = -5The system of equations can be solved by elimination:2a + 3a = -65a = -6a = -6/5substitute the value of a in any of the two original equations to find the value of b:2(-6/5) + 7b = -1-12/5 + 1 = -7b-7/5 = -7bb= 1/5

Subtract 8 from each side: 3a = 33 Divide each side by 3: a = 11

Subtract 6 from each side: 3a = 9Divide each side by 3: a = 3Job done.

Yes.

12+1.5a = 3a 12 = 3a-1.5a 12 = 1.5a Divide both sides by 1.5 to find the value of a: a = 8

Subtract 8 from each side: 3a = 33 Divide each side by 3: a = 11

The solution for the value of 3a would be -3. The equation would be 6a + 3(4) = 2.

Subtract 6 from each side: 3a = 9Divide each side by 3: a = 3Job done.

a + 3a + 5a = 180 9a =180 a = 20

2a + 3a + 4 = 5a + 4

3a=1divide both sides by 3a=1/3
