Answer:

a/b = 12

Step-by-step explanation:

2a -5b          1

------------- = -----

3a+2b             2

We can use cross products to get in the form of a /b

2(2a-5b) = 1(3a+2b)

Distribute

4a -10b=3a+2b

Get the a terms on the left and the b terms on the right

Subtract 3a from each side

4a-3a -10b=3a-3a+2b

a - 10b = 2b

Add 10b to each side

a-10b +10b = 2b+10b

a = 12 b

Divide each side by b

a/b = 12b/b

a/b = 12
