a=5
That factors to (2a - 7)(2a + 9)
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?
8b -2a
2a/3=8+4a2a=3(8+4a) 2a=24+12a -10a=24 a=-24/10 a=-12/5
2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
a=5
4a
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
Solve the following equation for A : 2A/3 = 8 + 4A
That factors to (2a - 7)(2a + 9)
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?
8b -2a
6a+1=2a+25 Subtract 2a from both sides 4a+1=25 Subtract 1 from both sides 4a=24 Divide both sides by 4 a=6 That is your final answer.
The expression is: (4a+b)/(2a-5b)
2a+6b
