Answer:
(4b - 6a + 9) / 6ab.
Step-by-step explanation:
The lowest common denominator of 3a, b and 2ab = 6ab
Now to get the numerator we divide each of the 3 denominators into 6ab and multiply the result by the corresponding numerator:
So we have:
2/3a - 1/b + 3/2ab
= (2*2b - 6a +3*3) / 6ab
= (4b - 6a + 9) / 6ab.
Answer:
11=1.632993162
12=0.5477225575
13=2.415229458
im not completely sure but i think 8=7.348469228
9=7.745966692 (not completely sure)
10=9.38083152(not completely sure)

Hope this helped :)
2a - 5b = 1
3a + 5b = 14
Let's solve this system using elimination. Add the equations together to cancel the b-terms, then solve for a.
2a - 5b = 1
3a + 5b = 14
+___________
5a - 0 = 15
5a = 15
a = 3
Next, plug 3 for a into either of the equations and solve for b.
2a - 5b = 1
2(3) - 5b = 1
6 - 5b = 1
- 5b = -5
b = 1
Lastly, check all work by plugging both values for their respective variables.
2a - 5b = 1
2(3) - 5(1) = 1
6 - 5 = 1 -- This is true
3a + 5b = 14
3(3) + 5(1) = 14
9 + 5 = 14 -- This is true
The solution to the system of equations is (3, 1).
