2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
The expression is: (4a+b)/(2a-5b)
2a+6b

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

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