a=5
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2

Not sure why it is 3a2- if you mean 3*a*2, then: 3*a*2=6a (6a-2a)+5-2(a (or a2)+a)=1 4a+5-(2a+a)=1 4a+5-2a-a=1 Then take the 5 over (remember, the +5 become -5 when transposed): 4a-2a-a=1-5 Solving the equations on both sides gives: a=-4 Is this your answer?
depends what 'a' =
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
a=5
a+b+2+3=5+a+b
2a-3+4b-2a-b-3+5=3b-1
A equals 20.
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2

3b -1
9a +8 -2a -3 -5a = 2a +5
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
