a=5
It is: (2*3)+5 = 11
It is [(2a+2h+5) - (2a+5)]/h = 2h/h = 2
2a/3=8+4a2a=3(8+4a) 2a=24+12a -10a=24 a=-24/10 a=-12/5
2a-5
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
a+b+2+3=5+a+b
A equals 20.
2a-3+4b-2a-b-3+5=3b-1
2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
9a +8 -2a -3 -5a = 2a +5

depends what 'a' =
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?
3b -1
