8/3 is your simplified answer
A+b 5
------- = ---
2a-b 4
b 5
-------- = ---- => 9b = 5a+45 => b = (5a+45)/9
a+9 9
a+b 5
------- = --- => 4a+4b = 10a-5b
2a-b 4
9b = 6a
9(5a+45) =6a divide both sides by 3
3(5a+45) = 2a
15a +135 = 2a
13a = -135
a = -135/13 = -10,38
a= -10,38
9b=6a
3b=2a
3b = 2(-10,38)
3b = -20,76
b = -20,76/3
b = -6,92
hope this helped
