2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14

2a = 8 + 4aSubtract 8 from each side:2a - 8 = 4aSubtract 2a from each side:-8 = 2aDivide each side by 2:-4 = a

a=5

4a

The value of a is -7

Solve the following equation for A : 2A/3 = 8 + 4A

That factors to (2a - 7)(2a + 9)

6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b

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.

2a+6b

11a+7b-(3b-2a)

58

The expression is: (4a+b)/(2a-5b)

It is 2a-b simplified

2a/3=8+4a2a=3(8+4a) 2a=24+12a -10a=24 a=-24/10 a=-12/5

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?

2a-6a+9-4a+9

The answer is 4a^2.

sqrt(4a2) = 21plus or minus (2a) = 21plus or minus (a) = 10.5a = +10.5a = -10.5

2a + 2b = 160 But b = a + 40 so 2a + 2(a + 40) = 160 ie 2a + 2a + 80 = 160 or 4a = 80 ie a = 20 Then b = a + 40 gives b = 20 + 40 = 60 Solution: a = 20, b = 60

-4 + 10 + 6a - 2a + 3 9 + 4a

2a^3=8+4a2a^3-4a-8=0 a^3-2a-4=0 It occurred to me just now by looking at the equation that a=2 would work. And it does. So that's your answer.

a-b+a-b+2b+a = 4a

The GCF is 2a.
