Well, honey, the answer to "3 plus 2a equals" is simply "3 + 2a." I mean, come on now, it's right there in the question! Just leave it as is unless you want to simplify it further, but that's as far as I'm willing to go with math today, darling.
If ba = 2a + b , then find 23 + 32 +1
With the assumption your asking what a or b are in terms of each other. a=3b/(6b-2) b=2a/(6a-2)

(2a + 1)(4a2 - 2a + 1)
6a to the second power minus 8ab + 2a
a + a + a - 2a = 3a - 2a = a
2a+5a=3 7a=3 a=3/7 or .4286
We have, 2a + 24 = 30or, 2a = 30-24or, 2a = 6or, a = 6/2 = 3.Therefore, a equals 3 or simply a=3
a = 4
a=5
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
(4, 3)
a+b+2+3=5+a+b
2a + 1 = 3subtract 1 from both sides2a = 2divide both sides by 2a = 1
2a+5a+9a = 16a
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
yes, if a=42a+3=112x4=88+3=11
