98a + 5 + 6a = 104a + 5
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
36a2 - 60a + 25 = 36a2 - 30a - 30a + 25 = 6a(6a - 5) - 5(6a - 5) = (6a - 5)(6a - 5) = (6a - 5)2
6a - 13 = -5 Therefore, 6a = 8 a = 8/6 a = 1.3 recurring (that is, 1.3333..)
3(6a + 5) + 30 18a + 15 + 30 18a + 45
Oh, come on! 6a - 5a = a, 7 - 5 = 2
7+2+5= 14 35 42
the answer to that is 5
true
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?
